A major bridge collapsed in the US city of Baltimore after it was hit by a 289m-long cargo ship.
Six people remain missing after two others were rescued from the water following the disaster in the early hours of Tuesday morning.
Here’s everything we know about the incident so far.
What happened?
A large section of the 1.6 mile-long Francis Scott Key Bridge fell into the water after it was struck by a container ship, known as the Dali, at around 1.30am local time (5.30am UK time).
The vessel struck one of the bridge’s supports, causing the whole structure to collapse, sending the road surface and steel beams crashing into the water.
The National Transportation Safety Board is leading the investigation into what happened, with its chair Jennifer Homendy saying at least six people are still missing.
Eight people were initially unaccounted for – with one described as being in a “very serious condition” in hospital. The other was not injured.
The six missing are believed to be part of a construction crew that was repairing potholes on the bridge, the Maryland Department of Transportation has said.
All 22 crew members on board the ship, including the two pilots, have been accounted for and there were no reports of injuries.

What does the footage show?
Dramatic video shows the cargo vessel approaching the bridge before the structure collapses into the water.
Vehicles can be seen falling from the bridge.
An exact number has not been given, but Baltimore fire department’s communications chief Kevin Cartwright said multiple vehicles were on the bridge when it was struck by the ship, one of which was the size of an HGV.
US president Joe Biden said in a news conference hours after the collapse that personnel on the ship were able to alert the Maryland Department of Transportation that they had lost control of their vessel.
Mr Biden added this “undoubtedly saved lives” at it meant local authorities were able to close the bridge before it was struck.

Footage showing the moment bridge collapsed
What happened in the moments before the crash?
CCTV and marine tracking data shows the container ship lost power for about 60 seconds about four minutes before it hit the bridge. It appeared to adjust its course and start smoking before impact.
According to the timings on the CCTV, the vessel hit the structure at 1.28:44am – with the bridge collapsing four seconds later.
The operators of the Dali cargo ship issued a mayday call that the vessel had lost power moments before the crash, but the ship still headed toward the bridge at “a very, very rapid speed”, Maryland Governor Wes Moore said.
The ship was moving at eight knots, which is roughly 9mph, when it hit the structure, the governor said.
What do we know about the ship?
The Singapore-flagged container ship, known as Dali, was headed to Colombo in Sri Lanka at the time of the collision.
Synergy Marine Group, the company which manages the ship, said it hit the bridge while under the control of two pilots.
The firm said the exact cause of the incident was yet to be determined.
The Dali was previously involved in a minor incident when it hit a quay at the Port of Antwerp in Belgium in 2016, according to Vessel Finder and maritime accident site Shipwrecklog.
An inspection of the Dali last June at a port in Chile identified a problem with the ship’s “propulsion and auxiliary machinery”, according to Equasis, a shipping information system.
The deficiency involved gauges and thermometers, but the website’s online records did not elaborate.
The most recent inspection listed for the Dali was conducted by the US Coast Guard in New York on 13 September 2023. The “standard examination” did not identify any deficiencies, according to the Equasis data.
What do we know about the bridge itself?
Last June, federal inspectors rated the 47-year-old bridge to be in fair condition. But the structure did not appear to have pier protection to withstand the crash, experts said.
“If a bridge pier without adequate protection is hit by a ship of this size, there is very little that the bridge could do,” according to Virginia Tech engineering professor Roberto Leon.
Built in 1977 and referred to locally as the Key Bridge, it was named after the author of the American national anthem.

All ship traffic into and out of the Port of Baltimore has been suspended until further notice, though the port remains open to trucks, Maryland Transportation Secretary Paul Wiedefeld said.
Last year, the port handled a record 52.3m tons of foreign cargo worth $80bn (£63bn), according to the state. In addition to cargo, more than 444,000 passengers cruised out of the port in 2023.
The port is a major east coast hub for shipping. The bridge spans the Patapsco River, which massive cargo ships use to reach the Chesapeake Bay and then the Atlantic Ocean.
The Dali was headed from Baltimore to Colombo, Sri Lanka, and flying under a Singapore flag, according to data from Marine Traffic.
President Biden said that he plans to travel to Baltimore “as quickly as I can” and that he expects the federal government to pick up the entire cost of rebuilding the bridge.

Timeline of Baltimore bridge collapse
Has this ever happened before?
From 1960 to 2015, there were 35 major bridge collapses worldwide due to ship or barge collisions, with a total of 342 people killed, according to a 2018 report from the World Association for Waterborne Transport Infrastructure.
Eighteen of those collapses happened in the United States.
Among them were a 2002 incident in which a barge struck the Interstate 40 bridge over the Arkansas River at Webbers Falls, Oklahoma, sending vehicles plunging into the water. Fourteen people died and 11 were injured.
In 2001, a tugboat and barge struck the Queen Isabella Causeway in Port Isabel, Texas, causing a section of the bridge to tumble 80 feet into the bay below. Eight people were killed.
In 1993, barges being pushed by a towboat in dense fog hit and displaced the Big Bayou Canot railroad bridge near Mobile, Alabama.
Minutes later, an Amtrak train with 220 people onboard reached the displaced bridge and derailed, killing 47 people and injuring 103 others.
The IDF has admitted to mistakenly identifying a convoy of aid workers as a threat – following the emergence of a video which proved their ambulances were clearly marked when Israeli troops opened fire on them.
The bodies of 15 aid workers – including eight medics working for the Palestine Red Crescent Society (PRCS) – were found in a “mass grave” after the incident, according to the head of the UN Office for Coordination of Humanitarian Affairs Jonathan Whittall.
The Israeli military originally claimed an investigation found the vehicles did not have any headlights or emergency signals and were therefore targeted as they looked “suspicious”.
But video footage obtained by the PRCS, and verified by Sky News, showed the ambulances and a fire vehicle clearly marked with flashing red lights.
In a briefing from the IDF, they said the ambulances arrived in the Tel Sultan neighbourhood in Rafah shortly after a Hamas police vehicle drove through.

An IDF surveillance aircraft was watching the movement of the ambulances and notified troops on the ground. The IDF said it will not be releasing that footage.
When the ambulances arrived, the soldiers opened fire, thinking the medics were a threat, according to the IDF.
The soldiers were surprised by the convoy stopping on the road and several people getting out quickly and running, the IDF claimed, adding the soldiers were unaware the suspects were in fact unarmed medics.
An Israeli military official would not say how far away troops were when they fired on the vehicles.
The IDF acknowledged that its statement claiming that the ambulances had their lights off was incorrect, and was based on the testimony from the soldiers in the incident.
The newly emerged video footage showed that the ambulances were clearly identifiable and had their lights on, the IDF said.
The IDF added that there will be a re-investigation to look into this discrepancy.

Addressing the fact the aid workers’ bodies were buried in a mass grave, the IDF said in its briefing this is an approved and regular practice to prevent wild dogs and other animals from eating the corpses.
The IDF could not explain why the ambulances were also buried.
The IDF said six of the 15 people killed were linked to Hamas, but revealed no detail to support the claim.

Bodies of aid workers found in Gaza
The newly emerged footage of the incident was discovered on a phone belonging to one of the workers who was killed, PRCS president Dr Younis Al Khatib said.
“His phone was found with his body and he recorded the whole event,” he said. “His last words before being shot, ‘Forgive me, mom. I just wanted to help people. I wanted to save lives’.”
Sky News used an aftermath video and satellite imagery to verify the location and timing of the newly emerged footage of the incident.

Aid worker attacks increasing
It was filmed on 23 March north of Rafah and shows a convoy of marked ambulances and a fire-fighting vehicle travelling south along a road towards the city centre. All the vehicles visible in the convoy have their flashing lights on.
The footage was filmed early in the morning, with a satellite image seen by Sky News taken at 9.48am local time on the same day showing a group of vehicles bunched together off the road.
Ukrainian President Volodymyr Zelenskyy has hit out at the US over its “weak” response to lethal Russian attacks on his hometown on Friday.
President Zelenskyy posted a lengthy and emotional statement on X about Russia’s strikes on Kryvyi Rih, which killed 19 people.
Meanwhile Ukrainian drones hit an explosives factory in Russia’s Samara region in an overnight strike, a member of Ukraine’s SBU security service told Reuters.
In his post, President Zelenskyy accused the United States of being “afraid” to name-check Russia in its comment on the attack.
“Unfortunately, the reaction of the American Embassy is unpleasantly surprising: such a strong country, such a strong people – and such a weak reaction,” he wrote on X.
“They are even afraid to say the word “Russian” when talking about the missile that killed children.”
America’s ambassador to Ukraine Bridget Brink had written on X: “Horrified that tonight a ballistic missile struck near a playground and restaurant in Kryvyi Rih.
“More than 50 people injured and 16 killed, including 6 children. This is why the war must end.”

Strike on Zelenskyy’s home city
President Zelenskyy went on in his post to say: “Yes, the war must end. But in order to end it, we must not be afraid to call a spade a spade.
“We must not be afraid to put pressure on the only one who continues this war and ignores all the world’s proposals to end it. We must put pressure on Russia, which chooses to kill children instead of a ceasefire.”
Grandmother ‘burned to death in her home’
Oleksandr Vilkul, head of the city’s defense council, said the missile attack, followed by a drone attack, had killed 19 people, including nine children.
“The Iskander-M missile strike with cluster munitions at the children’s playground in the residential area, to make the shrapnel fly further apart, killed 18 people.
“One grandmother was burnt to death in her house after Shahed’s direct hit.”
Russia’s defence ministry said it had struck a military gathering in a restaurant – an assertion rebutted by the Ukrainian military as misinformation.
“The missile hit right on the street – around ordinary houses, a playground, shops, a restaurant,” President Zelenskyy wrote.
Mr Zelenskyy also detailed the child victims of the attack including “Konstantin, who will be 16 forever” and “Arina, who will also be 7 forever”.
The UK’s chief of the defence staff Sir Tony Radakin said he had met the Ukrainian leader on Friday, along with French armed forces leader General Thierry Burkhard.
“Britain and France are coming together & Europe is stepping up in a way that is real & substantial, with 200 planners from 30 nations working to strengthen Ukraine’s long term security,” Sir Tony wrote.
Global financial markets gave a clear vote of no-confidence in President Trump’s economic policy.
The damage it will do is obvious: costs for companies will rise, hitting their earnings.
The consequences will ripple throughout the global economy, with economists now raising their expectations for a recession, not only in the US, but across the world.
