A major bridge in the US city of Baltimore has collapsed into the Patapsco River after a container ship crashed into it.
The bridge snapped and plunged into the water at about 01:30 ET (05:30 GMT) along with vehicles and people.
A huge search operation is under way for six missing people, authorities say, while two others have been pulled from the water.
All of them are believed to be part of a construction crew that was repairing potholes at the time the bridge collapsed.
The ship is now wedged into debris from the Francis Scott Key Bridge, which is 3km (1.6 miles) long and part of a major highway.
It suffered a "power issue" and issued a distress call moments before the crash, officials say, but was travelling too quickly to change course.
Maryland Governor Wes Moore says the bridge will be rebuilt "in a way that remembers the people this tragedy has impacted".
A mayday signal was sent when the ship was approaching the bridge, which gave authorities time to stop cars driving onto the bridge and "saved lives", Governor Moore said.
The governor said the vessel was moving at 8 knots, roughly 9mph (15km/h), which he says was "very, very rapid".
The crew on board the vessel, which is a Singapore-flagged container ship called Dali, told authorities they were having a power issue moments before the ship crashed.
The FBI says there is no credible link to terrorism, and the incident is believed to be an accident.
The Port of Baltimore remains closed to ships, and officials say they are unsure when it will reopen.
President Biden has said his government will cover the "entire cost" of rebuilding the bridge and getting the port functioning again.
