Inside the protesters’ encampment at UCLA, beneath the glow of hanging flashlights and a deafening backdrop of exploding flash-bangs, OB-GYN resident Elaine Chan suddenly felt like a battlefield medic.

Police were pushing into the camp after an hours-long standoff. Chan, 31, a medical tent volunteer, said protesters limped in with severe puncture wounds, but there was little hope of getting them to a hospital through the chaos outside. Chan suspects the injuries were caused by rubber bullets or other "less lethal" projectiles, which police have confirmed were fired at protesters.

"It would pierce through skin and gouge deep into people's bodies," she said. "All of them were profusely bleeding. In OB-GYN we don't treat rubber bullets. … I couldn't believe that this was allowed to be [done to] civilians — students — without protective gear."

The UCLA protest, which gathered thousands in opposition to Israel's ongoing bombing of Gaza, began in April and grew to a dangerous crescendo this month when counterprotesters and police clashed with the activists and their supporters.

In interviews with KFF Health News, Chan and three other volunteer medics described treating protesters with bleeding wounds, head injuries, and suspected broken bones in a makeshift clinic cobbled together in tents with no electricity or running water. The medical tents were staffed day and night by a rotating team of doctors, nurses, medical students, EMTs, and volunteers with no formal medical training.

At times, the escalating violence outside the tent isolated injured protesters from access to ambulances, the medics said, so the wounded walked to a nearby hospital or were carried beyond the borders of the protest so they could be driven to the emergency room.

"I've never been in a setting where we're blocked from getting higher level of care," Chan said. "That was terrifying to me."

Three of the medics interviewed by KFF Health News said they were present when police swept the encampment May 2 and described multiple injuries that appeared to have been caused by "less lethal" projectiles.

Less lethal projectiles — including beanbags filled with metal pellets, sponge-tipped rounds, and projectiles commonly known as rubber bullets — are used by police to subdue suspects or disperse crowds or protests. Police drew widespread condemnation for using the weapons against Black Lives Matter demonstrations that swept the country after the killing of George Floyd in 2020. Although the name of these weapons downplays their danger, less lethal projectiles can travel upward of 200 mph and have a documented potential to injure, maim, or kill.

The medics' interviews directly contradict an account from the Los Angeles Police Department. After police cleared the encampment, LAPD Chief Dominic Choi said in a post on the social platform X that there were "no serious injuries to officers or protestors” as police moved in and made more than 200 arrests.

In response to questions from KFF Health News, both the LAPD and California Highway Patrol said in emailed statements that they would investigate how their officers responded to the protest. The LAPD statement said the agency was conducting a review of how it and other law enforcement agencies responded, which would lead to a "detailed report."

The Highway Patrol statement said officers warned the encampment that "non-lethal rounds" may be used if protesters did not disperse, and after some became an "immediate threat" by "launching objects and weapons," some officers used "kinetic specialty rounds to protect themselves, other officers, and members of the public." One officer received minor injuries, according to the statement.

Video footage that circulated online after the protest appeared to show a Highway Patrol officer firing less lethal projectiles at protesters with a shotgun.

"The use of force and any incident involving the use of a weapon by CHP personnel is a serious matter, and the CHP will conduct a fair and impartial investigation to ensure that actions were consistent with policy and the law," the Highway Patrol said in its statement.

The UCLA Police Department, which was also involved with the protest response, did not respond to requests for comment.

Jack Fukushima, 28, a UCLA medical student and volunteer medic, said he witnessed a police officer shoot at least two protesters with less lethal projectiles, including a man who collapsed after being hit "square in the chest." Fukushima said he and other medics escorted the stunned man to the medical tent then returned to the front lines to look for more injured.

"It did really feel like a war," Fukushima said. "To be met with such police brutality was so disheartening."

Back on the front line, police had breached the borders of the encampment and begun to scrum with protesters, Fukushima said. He said he saw the same officer who had fired earlier shoot another protester in the neck.

The protester dropped to the ground. Fukushima assumed the worst and rushed to his side.

"I find him, and I'm like, 'Hey, are you OK?'" Fukushima said. "To the point of courage of these undergrads, he's like, 'Yeah, it's not my first time.' And then just jumps right back in."

Sonia Raghuram, 27, another medical student stationed in the tent, said that during the police sweep she tended to a protester with an open puncture wound on their back, another with a quarter-sized contusion in the center of their chest, and a third with a "gushing" cut over their right eye and possible broken rib. Raghuram said patients told her the wounds were caused by police projectiles, which she said matched the severity of their injuries.

The patients made it clear the police officers were closing in on the medical tent, Raghuram said, but she stayed put.

"We will never leave a patient," she said, describing the mantra in the medical tent. "I don't care if we get arrested. If I'm taking care of a patient, that's the thing that comes first."

The UCLA protest is one of many that have been held on college campuses across the country as students opposed to Israel's ongoing war in Gaza demand universities support a ceasefire or divest from companies tied to Israel. Police have used force to remove protesters at Columbia University, Emory University, and the universities of Arizona, Utah, and South Florida, among others.

At UCLA, student protesters set up a tent encampment on April 25 in a grassy plaza outside the campus's Royce Hall theater, eventually drawing thousands of supporters, according to the Los Angeles Times. Days later, a "violent mob" of counterprotesters "attacked the camp," the Times reported, attempting to tear down barricades along its borders and throwing fireworks at the tents inside.

The following night, police issued an unlawful assembly order, then swept the encampment in the early hours of May 2, clearing tents and arresting hundreds by dawn.

Police have been widely criticized for not intervening as the clash between protesters and counterprotesters dragged on for hours. The University of California system announced it has hired an independent policing consultant to investigate the violence and "resolve unanswered questions about UCLA's planning and protocols, as well as the mutual aid response."

Charlotte Austin, 34, a surgery resident, said that as counterprotesters were attacking she also saw about 10 private campus security officers stand by, "hands in their pockets," as students were bashed and bloodied.

Austin said she treated patients with cuts to the face and possible skull fractures. The medical tent sent at least 20 people to the hospital that evening, she said.

"Any medical professional would describe these as serious injuries," Austin said. "There were people who required hospitalization — not just a visit to the emergency room — but actual hospitalization." Police tactics 'lawful but awful'

UCLA protesters are far from the first to be injured by less lethal projectiles.

In recent years, police across the U.S. have repeatedly fired these weapons at protesters, with virtually no overarching standards governing their use or safety. Cities have spent millions to settle lawsuits from the injured. Some of the wounded have never been the same.

During the nationwide protests following the police killing of George Floyd in 2020, at least 60 protesters sustained serious injuries — including blinding and a broken jaw — from being shot with these projectiles, sometimes in apparent violations of police department policies, according to a joint investigation by KFF Health News and USA Today.

In 2004, in Boston, a college student celebrating a Red Sox victory was killed by a projectile filled with pepper-based irritant when it tore through her eye and into her brain.

"They're called less lethal for a reason," said Jim Bueermann, a former police chief of Redlands, California, who now leads the Future Policing Institute. "They can kill you."

Bueermann, who reviewed video footage of the police response at UCLA at the request of KFF Health News, said the footage shows California Highway Patrol officers firing beanbag rounds from a shotgun. Bueermann said the footage did not provide enough context to determine if the projectiles were being used "reasonably," which is a standard established by federal courts, or being fired "indiscriminately," which was outlawed by a California law in 2021.

"There is a saying in policing — 'lawful but awful' — meaning that it was reasonable under the legal standards but it looks terrible," Bueermann said. "And I think a cop racking multiple rounds into a shotgun, firing into protesters, doesn't look very good."

How Google put together the pieces for its AI comeback

Vcg | Visual China Group | Getty Images

When ChatGPT launched in 2022, Google was caught flatfooted, but the launch of Gemini 3 and the Ironwood AI chip this month has experts raving about Alphabet’s AI comeback. 

Google kicked off November by unveiling Ironwood, the seventh generation of its tensor processing units, or TPUs, that the company says lets customers “run and scale the largest, most data-intensive models in existence.” And last week, Google launched Gemini 3, its latest artificial intelligence model, saying it requires “less prompting” and provides smarter answers than its predecessors.

Salesforce CEO Marc Benioff captured the excitement around Gemini 3 with a Sunday post on X, saying that despite using OpenAI’s ChatGPT daily for three years, he wasn’t going back after two hours of using Gemini 3.

“The leap is insane,” wrote Benioff, whose company has partnerships with Google, OpenAI and other frontier AI model providers. “Everything is sharper and faster. It feels like the world just changed, again.”

Most tech stocks were down to start the week, except for one: Alphabet.

Shares of the Google parent surged more than 5% on Monday, adding to last week’s gain of more than 8%. Warren Buffett’s Berkshire Hathaway revealed earlier this month that it owns a $4.3 billion stake in Alphabet as of the end of the third quarter.

Alphabet shares are up nearly 70% this year and have outperformed Meta’s by more than 50 percentage points this year, and last week, Alphabet’s market cap surpassed Microsoft’s.

All of this came despite Nvidia reporting stronger-than-expect revenue and guidance in its third-quarter earnings last week.

“You may be asking why almost all of the AI stocks we cover are selling off after such good news from Nvidia,” Melius Research analyst Ben Reitzes wrote in a note Monday, referring to Nvidia’s positive third quarter earnings last week. “There is one real reason for worry and it is the ‘AI comeback’ of Alphabet.” 

But while Google appears to have regained the edge, its lead over rivals remains razor thin in the gruelingly competitive AI market, experts said.

Putting the pieces together

With Gemini 3 and Ironwood, Google CEO Sundar Pichai appears to have finally put the pieces together for the company’s AI offerings, said Michael Nathanson, co-founder of equity research firm Moffett Nathanson. Google is serving a broad range of customers from consumers to enterprise, something the company initially struggled to do after the arrival of ChatGPT.

“Three years ago, they were seen as kind of lost and there were all these hot takes saying they lost their way and Sundar is a failure,” Nathanson said. “Now, they have a huge leg up.”

The company had a number of AI product mishaps in its initial attempts to catch up with OpenAI. In 2024 alone, Google had to pull its image generation product Imagen 2 for several months after users discovered a number of historical inaccuracies. The launch of AI Overviews caused a similar reaction when users discovered it gave faulty advice, which the company later remedied with additional guardrails.

“There was a lot of fumbling, and they were scrambling,” said Gil Luria, managing director at technology research firm DA Davidson. “But they had the tech in the pantry, and it was just a matter of getting it all together and shipped.”

Of particular note is how quickly Google launched Gemini 3 after the spring release of Gemini 2.5, which was already considered an impressive model. The hyper-realistic image generation features of Nano Banana is another notch in Google’s belt. After the company initially launched the image generation tool, Gemini shot to the top of the Apple App Store in September, dethroning ChatGPT.

And after the launch of Gemini 3, Google released Nano Banana Pro last week.

Google’s ownership of YouTube and all the content on the video platform gives the company an edge when it comes to training models for image and video generation.

“The amount of video and current data that Google has, that’s really a huge competitive advantage,” said Mike Gualtieri, vice president and principal analyst for Forrester Research. “I don’t see how OpenAI and Anthropic can overcome that.”

Additionally, Google has successfully incorporated its AI models into its enterprise products, driving sales for the company’s cloud unit. In its third quarter earnings results last month, Google reached its first $100 billion quarter, boosted by its cloud growth. The company’s cloud unit, which houses its AI services, showed solid growth and a $155 billion backlog from customers.

And it’s not just the AI models. Google is also garnering attention with its AI chips.

Google says Ironwood is nearly 30 times more power efficient than its first TPU from 2018. Google’s ASIC chips are emerging as the company’s secret weapon in the AI wars and have helped it notch recent deals worth billions with customers such as Anthropic.

After a report said that Meta could strike a deal with Google to use its TPUs for the social media company’s data centers, Nvidia saw its stock drop 3% on Tuesday, prompting the chipmaker to post a response on social media.

With the rise of Google’s TPUs, Nvidia may no longer have the AI chips market cornered.

“The advantage of having the whole stack is you can optimize your model to work specifically well on a TPU chip and you’re building everything to a more optimally designed,” said Luria.

The company’s ability to serve AI enterprise customers with its TPUs and Google Cloud offerings as well as its incorporation of Gemini 3 throughout its consumer products is driving Wall Street’s enthusiasm.

Experts who spoke with CNBC said the competitive landscape is broader than just one AI winner, but they added that it’s become increasingly expensive for multiple companies to prove success.

Tight competition

Despite these wins, Google is still in fierce competition with other AI companies, experts said.

“Having the state of the art model for a few days doesn’t mean they’ve won to the extent that the stock market is implying,” Luria said, pointing to Anthropic’s new Opus 4.5 model launched Monday.

Earlier this month, OpenAI also announced two updates to its GPT-5 model to make it “warmer by default and more conversational” as well as “more efficient and easier to understand in everyday use,” the company said.

“The frontier models still seem to be neck and neck in some ways,” Forrester Research’s Gualtieri said.

The competitive edge will likely go to the companies willing to spend more money given the expenses of the AI race, experts said. In their earnings reports last month, AlphabetMetaMicrosoft and Amazon each lifted their guidance for capital expenditures. They collectively expect that number to reach more than $380 billion this year.

“These companies are spending a lot of money assuming there’s gonna be a winner take all when in reality we may end up with frontier models being a commodity and several will be interchangeable,” Luria said.

For Google, maintaining a lead in AI won’t be without challenges.

Company executives told employees earlier this month that Google has to double its serving capacity every six month to meet demand for AI services and run its frontier models, CNBC reported last week.

“The competition in AI infrastructure is the most critical and also the most expensive part of the AI race,” Google Cloud Vice President Amin Vahdat told employees.

Although Google’s in-house TPUs have gotten increased attention as viable alternatives to Nvidia’s Blackwell chips, Nvidia still holds more than 90% of the AI chip market.

In its post on Tuesday, Nvidia pointed out that its chips are more flexible and powerful than ASIC chips, like Google’s Ironwood, which are typically designed for a single company or function.

And despite getting Salesforce’s Benioff to switch to Gemini, Google also has a lot of catching up to do with its consumer chat product, experts said, citing hallucinations and lower user numbers than OpenAI’s.

The Gemini app has 650 million monthly active users and AI Overviews has 2 billion monthly users, Google said last month. OpenAI, by comparison, said in August that ChatGPT hit 700 million users per week.  

“Yes, Google has got its act together,” Luria said. “But that doesn’t mean they’ve won.”

At least 65 dead and hundreds missing as police make arrests over Hong Kong fire

At least 65 people have been killed, and police have made several arrests, after a huge fire engulfed a high-rise residential complex in Hong Kong.

Authorities said nearly 300 people are also missing following the blaze at Wang Fuk Court in Tai Po – a suburban district with around 300,000 residents, near the border with mainland China.

A further 70 people have been injured, including more than 40 who were described as critically ill in hospital on Wednesday night. Around 900 people are also in shelters as a result of the blaze.

Deadly blaze destroys Hong Kong tower blocks

Police have alleged its cause could have been a “grossly negligent” construction firm using unsafe materials.

Three people – two directors and an engineering consultant – have been arrested on suspicion of manslaughter.

“We have reason to believe that the company’s responsible parties were grossly negligent, which led to this accident and caused the fire to spread uncontrollably, resulting in major casualties,” said police superintendent Eileen Chung. Police have not named the company.

The complex, built in the 1980s, had been under renovation for a year.

One firefighter was among those killed tackling the blaze, which broke out at 2.51pm local time on Wednesday.

Fire crews said they had doused the flames in all seven of the affected blocks by Thursday morning, and were searching each floor for survivors.

Records show the Wang Fuk Court site consists of eight blocks, with almost 2,000 flats housing around 4,800 residents, including many elderly people.

Families have been identifying the bodies of relatives while others have been visiting shelters in the area, searching for missing loved ones.

Hong Kong leader John Lee said on Thursday the government will set up a HK$300m (£29m) fund to help residents.

The cause of the fire is being investigated, but it appears to have started in bamboo scaffolding and construction mesh sheets and then spread across seven of the complex’s eight buildings – likely aided by windy conditions.

Bamboo scaffolding is commonly used in Hong Kong, but is in the process of being phased out because of safety concerns.

Hong Kong’s Association for the Rights of Industrial Accident Victims said there have been at least three fires involving bamboo scaffolding this year.

China’s state broadcaster CCTV said President Xi Jinping has urged an “all-out effort” to extinguish the fire and minimise casualties and losses.

Both the US and British Consulate Generals for Hong Kong have sent condolences to those affected, as has Taiwan’s president.

The number of dead is the highest in a Hong Kong fire since 1948, when 176 people were killed in a warehouse blaze.

The fire has prompted comparisons to the Grenfell Tower blaze which killed 72 people in 2017, blamed on flammable cladding, as well as failings by the government and the construction industry.

“Our hearts go out to all those affected by the horrific fire in Hong Kong,” the Grenfell United survivors’ group said on
social media.

“To the families, friends and communities, we stand with you. You are not alone.”

Washington DC shooting: Trump condemns 'monstrous' attack near White House - and says suspect is Afghan national

Donald Trump has called for every Afghan national who entered the US under the Biden administration to be investigated following the shooting of two National Guard troops near the White House.

The president said the “monstrous, ambush-style attack” was carried out by an Afghan national who arrived in September 2021 during America’s chaotic withdrawal from Kabul.

“This attack underscores the single greatest national security threat facing our nation,” Mr Trump said in an address to the nation from Florida.

He vowed to “reexamine every single alien” who has entered the US from Afghanistan under the previous government, and said: “I am determined to ensure the animal who perpetrated this atrocity will pay the steepest possible price.”

Suspect to face terror probe

America’s citizenship and immigration office said it had stopped processing all immigration requests relating to Afghan nationals indefinitely.

The suspect in custody is 29-year-old Rahmanullah Lakanwal.

Both guardsmen were shot in the head, according to NBC, citing senior officials briefed on the investigation.

Wednesday’s shooting – carried out with a handgun – will be investigated by the FBI as a possible act of terror.

The White House was placed into lockdown following the incident, while Mr Trump is away for Thanksgiving.

Victims in ‘critical condition’

West Virginia’s governor initially said both victims were members of his state’s National Guard and had died from their injuries – but later posted to say there were “conflicting reports about the condition of our two Guard members”.

Patrick Morrisey had said: “These brave West Virginians lost their lives in the service of their country.”

Hundreds of National Guard members have been patrolling the capital after Mr Trump issued an emergency order in August, which federalised the local police force and sent in the guard from eight states and the District of Columbia.

Mr Trump has announced an extra 500 troops will be deployed in the wake of Wednesday’s shooting.

FBI director Kash Patel said the troops were “brazenly attacked in a horrendous act of violence”.

At a news conference, he clarified they were in a “critical condition”.

Former president Joe Biden, who was heavily criticised by Mr Trump in his address, said he and his wife Jill were “heartbroken” by the shooting.

“Violence of any kind is unacceptable, and we must all stand united against it,” said a statement.

Analysis: Trump’s statement could embolden anti-immigration Americans

US correspondent Mark Stone said it was expected that Trump’s statement would have an update on the investigation and the victims’ condition.

“What struck me was the president’s decision to be so political and to make the point as he wanted to, it seemed, that this will now embolden him to find out who else might be here illegally, wherever they may be from,” Stone said.

“And he singled out Somalis in Minnesota, of course, a Democratic-run state.”

Stone said Trump’s statement could further embolden those who already hold anti-immigration sentiments.

“You might expect a leader in this sort of situation to deal with the facts as he knows them and to call for unity. But it’s not Trump’s style to do that.”

How the attack unfolded

Jeff Carroll, chief of the metropolitan police department in the area, said the attack began at 2.15pm local time (7.15pm in the UK) while National Guard members were on “high visibility patrols in the area”.

He said: “A suspect came around the corner, raised his arm with a firearm and discharged it at the National Guard.

“The National Guard members were… able to – after some back and forth – able to subdue the individual and bring them into custody.”

Washington DC mayor Muriel Bowser called the attack a “targeted shooting”.

The FBI was also on the scene, the agency’s director said.
