The Francis Scott Key Bridge collapsed into the Patapsco River in the early hours of Tuesday morning and sent several vehicles into the river, according to multiple outlets.

Baltimore City Fire Department spokesperson Kevin Cartwright toldCNNthat the collapse was a “mass casualty multi agency incident.”

“This is a dire emergency,” Cartwright told theAssociated Press. “Our focus right now is trying to rescue and recover these people.”

Rescue workers are searching for up to 20 people, according to CNN. “Unfortunately, we understand that there are up to 20 individuals who may be in the Patapsco River as well as multiple vehicles,” Cartwright told the outlet.

Speaking during a press conference on Tuesday morning, Baltimore Fire Department Chief James Wallace said two people had been rescued from the water, per CNN. One of the individuals was uninjured, while the second was transferred to the hospital in a “very serious condition.”

Wallace added that authorities are continuing to search for upwards of seven people. “We are still very much in an active search and rescue posture at this point, and we will continue to be for some time,” Wallace said, per the outlet.

Fire dept. spokesperson Cartwright toldWTOPthat at least seven vehicles had fallen into the river and a dive team had been deployed to help rescue those in the water.

Cartwright also told CNN that conditions were “unsafe” for rescuers due to “some cargo or retainers hanging from the bridge” following the collision with the 900-ft cargo ship.
