Baltimore Mayor declares state of emergency in response to Francis Scott Key Bridge collapse

Baltimore Mayor Brandon Scott on Tuesday declared a state of emergency in response to the Francis Scott Key Bridge collapse.

The mayor's declaration took effect at 9:00 a.m. ET and will unlock additional powers to respond to the crisis.

"Baltimore, I am officially declaring a local state of emergency in response to the collapse of our Key Bridge," Scott said in a statement. "Our teams are mobilizing resources and working swiftly to address this crisis and ensure the safety and well-being of our community."

Officials will soon deliver an update on search and rescue efforts in Baltimore Harbor.

A container ship struck one of the bridge's supports in the early morning on Tuesday, causing the bridge to snap and plunge into the Patapsco River. Several vehicles and workers were on the bridge at the time of its collapse. 

The U.S. Coast Guard and several law enforcement agencies are participating in search and rescue operations. Two people were pulled from the water, one in critical condition, officials said. 

Fire Chief James Wallace said authorities “may be looking for upwards of seven people” but said that number could change and other officials wouldn't give figures. It was not clear if the two rescued were included in the seven cited by the fire chief.
