At least seven people are still missing after the Baltimore Key Bridge collapse. Here’s everything we know

Rescuers are in a race against time as they desperately search for at least seven people who are feared to be in the water after a container ship collided with Baltimore’s Key Bridge, causing a “catastrophic collapse” while vehicles were still on the structure.

Two people have so far been pulled from the river. One was transported to a trauma unit and is in a serious condition, while the other had not reportedly suffered any injuries.

However, at least seven people are still missing and sonar technology has detected that at least seven vehicles were also thrown off the bridge and submerged in the water.

Officials say that rescue teams are working in harsh temperatures to try and find the missing people in the Patapsco River in an area 50-foot deep.

The Dali container ship is thought to have “lost propulsion” as it left Baltimore port, with the crew warning Maryland officials they had lost control of the almost 300-metre-long vessel and that a collision was possible, ABC News reported.

The situation has been described as a “developing mass casualty incident,” and the governor of Maryland has declared a state of emergency as multiple agencies waded through cold waters in the darkness of the early hours, searching amid debris for those missing in the aftermath of the horrific collapse.

Here’s what we know about the Baltimore bridge collapse:

At around 1.30am ET local time, the Singapore-flagged vessel Dali struck a column on the Francis Scott Key Bridge, leading multiple parts of the 1.6 mile-long bridge to tumble into the water.

A number of vehicles and possibly pedestrians were on the bridge at the time of the collision. There may also have been workers carrying out concrete deck repair on the bridge at the time.
