It wasn’t quite the day the Earth stood still, but those who witnessed a fiery asteroid briefly outshine the sun as it soared towards the Russian city of Chelyabinsk will almost certainly never forget it.
Comparable to the size of a house and travelling at a scintillating 11 miles per second, what was quickly dubbed the Chelyabinsk meteor arrived unannounced in a manner reminiscent of a science-fiction disaster film. It was an unnerving spectacle.
Dashcam footage from the morning of 15 February 2013, in the central Russian city close to the Ural Mountains, shows the small asteroid entering the Earth’s atmosphere before it exploded with 30 times more force than the US atom bomb that destroyed Hiroshima in the Second World War.
Windows shattered, buildings were damaged, and hundreds of people were injured – but Chelyabinsk got lucky.
“Had it been directly over the city, the damage would have been worse,” warns NASA‘s planetary defence officer Lindley Johnson. “It was definitely a wake-up call.”
‘We’ve never seen anything like it since’
Working with partners like the European Space Agency, Mr Johnson’s department warns of any impacts to Earth by comets and asteroids and guides the response.
A standard test case was a “shooting star” asteroid that soared above the English Channel this week, which was tracked and publicised in advance, so people could see it for themselves.
Chelyabinsk was no standard test case.

“We’ve never seen anything like it since we started working in this area,” says Mr Johnson, whose office inside the US space agency was only established in 2016.
“It was daylight, clearly visible in the daytime sky, and that doesn’t happen very often.
“It came in on the daylight side of Earth, and we had no chance of being able to detect it ahead of time with the ground-based observatories that we used to find these objects at that time.”

What are the chances of another Chelyabinsk?
Mr Johnson was in Vienna, Austria, on the day of Chelyabinsk’s arrival, attending meetings of UN members of the Committee on the Peaceful Uses of Outer Space.
It didn’t take long for recommendations on how to protect the Earth from such events to be endorsed, including an international asteroid warning network.
Professor Alan Fitzsimmons, of Queen’s University, Belfast, is an expert in these so-called near-Earth objects, and a committed member of the “planetary defence community”.
“We’re very open about what we find and our current state of knowledge about potential impact risks,” he says. “All asteroids that are detected are announced on public websites.
“Technology has come a long way in terms of how well you can detect asteroids, even as small as Chelyabinsk, but there’s still the chance that one could sneak through. And it’s quite likely that the next significant asteroid we have would be unannounced.”

How are we protecting ourselves?
Chelyabinsk was considered a small asteroid – that and its arrival during daylight is why it was hard to see coming.
“We’re still vulnerable to those that are coming from the sun,” admits Mr Johnson.
“Most of these objects come from a main belt of asteroids out between Mars and Jupiter, and when they’re coming inbound into the inner solar system, we can find them in the night sky. But when they loop around the sun and come back out, that’s when we’re vulnerable.”
The key to being able to expect the unexpected, he says, is space-based observation.
NASA is working on the $1.2bn (£985m) Near-Earth Object (NEO) Surveyor for launch in 2028, which will be the first space telescope specifically designed to hunt asteroids and comets that may be potential hazards to Earth.
Even then, Chelyabinsk was far smaller than the asteroids NEO will focus on. Amy Mainzer, NEO Surveyor’s principal investigator, says it will prioritise “finding the one asteroid that could cause a really bad day for a lot of people”.
Also in the repertoire is the Double Asteroid Redirection Test (Dart) spacecraft. During testing last year, it was deliberately crashed into an asteroid and successfully altered its orbit.

What if another one gets through?
Chelyabinsk’s arrival showcased the importance of quick and effective communication – its arrival was rapidly documented around the world, Russian scientists shared their findings, fragments have been collected, studied, and found new homes, and the event informed international policy.
Prof Fitzsimmons says such transparency and coordination would again be vital, perhaps even more so in an age where misinformation can quickly spread.
“When these kinds of events are determined to be of natural causes, the flow of information is pretty good even in today’s environment,” says Mr Johnson. “But there certainly is concern in knowing quickly that it’s a natural event versus something that’s human caused.
“The entry and detonation of these objects by the heat pressure in the atmosphere, to the human eye, can look very much like an attack, whereas sophisticated instrumentation rapidly discerns the difference.”

‘A long way to go to find them all’
At the moment, there are some 31,000 asteroids being tracked – up from around 9,500 in 2013.
It’s a sign of how much more seriously the prospect of a dangerous impact has been taken since Chelyabinsk, which was the largest and best recorded asteroid impact on Earth since 1908. That was when an asteroid exploded over Siberia, flattening some 80 million trees in a blast equivalent to 15 million tons of dynamite.
Not being near a built-up area was again incredibly fortunate.
Russia’s sheer size is all that’s made it a relative hotbed of historic asteroid activity. With 70% of the Earth being covered by water, odds are that most asteroids – detected or not – end up in the ocean. An impact like Chelyabinsk is probably a once-in-a-century event, reckons NASA.
None of the 31,000 asteroids we know of are predicted to hit Earth in the next 100 years, says Prof Fitzsimmons, but there’s still “a long way to go to find them all”.
“But I’ll reassure you – I still come into work and pay into my pension plan.”
The Israeli military has said its investigation into the killing of aid workers in Gaza has found there were “several professional failures, breaches of orders, and a failure to fully report the incident”.
A commanding officer will be reprimanded and a deputy commander will be dismissed following the military investigation, the Israel Defence Forces (IDF) said.
Fifteen aid workers were shot dead by Israeli troops who opened fire on a convoy of vehicles, including ambulances, on 23 March.
They were then buried in a shallow grave where their bodies were found a week later by officials from the United Nations and the Palestinian Red Crescent.
The probe’s findings come after a Sky News investigation earlier this week revealed how the deadly attack unfolded, contradicting Israel’s official account of the killings.
At first, Israel claimed the medics’ vehicles did not have emergency signals on when troops fired their shots, but later backtracked.
Mobile phone footage which was recovered from one of the medics contradicted Israel’s initial account.
In a statement on Sunday, an IDF spokesperson said: “The Commanding Officer of the 14th Brigade will receive a reprimand, which will be recorded in his personal file, for his overall responsibility for the incident, including the procedure of combat and management of the scene afterward.
“The deputy commander of the Golani Reconnaissance Battalion will be dismissed from his position due to his responsibilities as the field commander in this incident and for providing an incomplete and inaccurate report during the debrief.”

‘Poor night visibility’
The investigation found that the deputy commander did not initially recognise the vehicles as ambulances “due to poor night visibility”, according to the spokesperson.
“Only later, after approaching the vehicles and scanning them, was it discovered that these were indeed rescue teams,” they added.
Probe looked at ‘three shooting incidents’
The IDF said that about an hour before the attack on the convoy, Israeli troops fired at what they “identified as a Hamas vehicle” and the forces “remained on high alert for further potential threats”.
In the convoy incident, the IDF said the soldiers “opened fire on suspects emerging from a fire truck and ambulances very close to the area in which the troops were operating, after perceiving an immediate and tangible threat”.
“Supporting surveillance” had reported five vehicles approaching rapidly and stopping near the troops, with passengers quickly disembarking, according to the IDF.
It said the deputy battalion commander “assessed the vehicles as employed by Hamas forces, who arrived to assist the first vehicle’s passengers”, adding that: “Under this impression and sense of threat, he ordered to open fire.”
According to the IDF, six of the 15 killed were “identified in a retrospective examination as Hamas terrorists”.
But the Sky News investigation found no evidence to support this claim.
The IDF also said there was a third incident about 15 minutes later where “the troops fired at a Palestinian UN vehicle due to operational errors in breach of regulations”.
“The troops’ commander initially reported the event, and additional details emerged later in the examination.”
Bodies were buried in mass grave
Eight Red Crescent personnel, six civil defence workers and a UN staff member were killed in the shooting on the convoy by troops carrying out operations in Tel al Sultan, a district of the southern Gaza city of Rafah.
Troops then bulldozed over the bodies along with their mangled vehicles, burying them in a mass grave.
‘Decision to crush vehicles was wrong’
The IDF statement said that at dawn it was decided to “gather and cover the bodies to prevent further harm and clear the vehicles from the route in preparation for civilian evacuation”.
The body removal and vehicle crushing were carried out by field commanders, according to the military.
Removing the bodies was reasonable under the circumstances, but the decision to crush the vehicles was wrong, the investigation concluded, and “in general there was no attempt to conceal the event”.
The probe also found that “the [gun]fire in the first two incidents resulted from an operational misunderstanding by the troops, who believed they faced a tangible threat from enemy forces. The third incident involved a breach of orders during a combat setting”.
Pope Francis has made his first significant public appearance since he left hospital, greeting cheering crowds from the popemobile.
He blessed the thousands of faithful gathered to celebrate Easter Sunday at the Vatican.
The 88-year-old pontiff appeared frail as he was wheeled out onto the balcony over the entrance of St Peter’s Basilica, before being driven in the popemobile through the crowds of faithful gathered in St Peter’s Square.
He was met with cheers, applause and chants of “Viva il Papa” – meaning long live the Pope.

“Brothers and sisters, Happy Easter!” Pope Francis managed to say, before an aide read the rest of his annual Urbi et Orbi blessing and speech, which called for an end to the conflicts in Ukraine and Gaza.
“May the risen Christ grant Ukraine, devastated by war, his Easter gift of peace, and encourage all parties involved to pursue efforts aimed at achieving a just and lasting peace,” the message said.

“In this Jubilee year, may Easter also be a fitting occasion for the liberation of prisoners of war and political prisoners!”

Crowds then stretched out their hands and filmed as the Pope was driven past in the special vehicle.
The popemobile stopped a number of times in order for the pontiff to bless babies and small children, appearing to also give them gifts.

Before the public appearance, the Pope “exchanged good wishes” with US vice president JD Vance during a private audience at the Vatican.

Mr Vance, who is in Rome with his family, also met with Pope Francis on Saturday, where the Vatican said there had been “an exchange of opinions” over international conflicts, migrants and prisoners.

Leading up to Easter, he skipped the solemn services of Good Friday and Holy Saturday. Before Sunday, his biggest outing had been a visit to Rome’s central prison to spend Holy Thursday with inmates.
He also missed the Easter Sunday open-air mass, which was led instead by Cardinal Angelo Comastri, the retired archpriest of St Peter’s Basilica.
As people take a break for the Easter holiday, in the Gaza Strip there is no respite from the 18-month-long war with Israel.
Gaza has a tiny Christian community of Greek Orthodox Christians, Catholics, Evangelicals, and Anglicans.
For Ramez al-Souri, the pain is unimaginable. His three children were killed by an Israeli airstrike, on an annex of Gaza’s Saint Porphyrius Greek Orthodox Church.
Palestinian health officials say the attack on 19 October 2023 killed 18 people inside the building.
“My home has changed completely because there are no smiles, no laughter, no joy,” Mr Al-Souri says.
“I lost my flower – my daughter Julie – and my boys Suhail and Majd. They were salt of the Earth.”
Shrouded in darkness
Julia was 12 years old, Suhial 14 and Majd 11.
It is a loss that never leaves Mr Al-Souri, and one shared by almost every family in Gaza.
Walking through the cemetery, he gently places a small bouquet of flowers on his children’s grave. Gunfire crackles in the distance. The neighbourhood is full of rubble and destruction.
“This Easter is no different than the last,” Mr Al-Souri says.
“We are tending to our wounds.
“We continue to hope for an end to this war and suffering, for the darkness over Gaza to finally lift.”
Mr Netanyahu said Israel has “no choice” but to keep fighting “for our very own existence until victory.”
Israel is calling for Hamas to disarm and to release 10 Israeli hostages in exchange for a 45-day ceasefire.
There are 59 hostages still inside Gaza. It is believed 24 of them are still alive.
Hamas has rejected the proposal. It argues Israel reneged on the first ceasefire deal by refusing to move to phase two of the agreement and withdraw Israeli troops from the Gaza Strip.

Netanyahu: ‘I will not give in’
A disaster on the ground
Since the ceasefire collapsed on 2 March, Israel’s bombing campaign has intensified.
Palestinian health officials say more than 1,700 people have been killed in the last month, and more than 90 people in the last 24 hours.
The humanitarian situation is a disaster. At the few remaining soup kitchens in Gaza, children scramble for food. They carry pots for their family and push forward trying to secure a bowl of lentils or rice.
Israel has blocked aid trucks from entering for the last seven weeks. It says it is to put pressure on Hamas.
But the pressure is being felt by civilians, creating what aid groups say is the most severe crisis Gaza has ever faced.
Israel has cut off vital supplies of food and medicine, but insists it is not using starvation as a weapon of war. It rejects any suggestion Gaza does not have enough food and accuses Hamas of stealing it.

‘We’re craving food’
Seven members of the Al-Asheh family are displaced and live in a tent in Deir al-Balah.
Twelve-year-old Ahmed says before the war he didn’t like lentils, now it is all he eats.
“Before the war, we used to have fruits, chicken, vegetables, everything was available. We were never hungry,” Ahmed explains.
“Now, we’re craving food, chicken – anything. The only thing we can eat now is what the soup kitchen provides.”

It is clear that ceasefire talks are going nowhere, and Israel has tightened its blockade and deepened its war.
More than 400,000 Palestinians have recently been displaced yet again as Israel has expanded a buffer zone inside Gaza, levelling houses to create a “security zone”.
For Palestinians, this constitutes a “land grab”.

Israeli forces encircle Rafah
‘A symbol of the world’s conscience’
Israel has also established another military corridor in southern Gaza, calling it Morag corridor.
The corridor is north of Rafah and has cut Gaza’s second-largest city off from the rest of the territory. Israel says it has now taken control of 30% of the Gaza Strip and insists it will not withdraw.
For Palestinians, the future has never looked more bleak. They are blockaded, displaced, struggling for food, water, basic sanitation and in constant search of safety.
“Gaza is calling on the world to stand by it,” Mr Al-Souri says.
“Gaza stands as a symbol of the world’s moral conscience.”
