The 751-foot CSX Coal bulk carrier exploded near Francis Scott Key bridge, which collapsed last year following a collision with another vessel.

An explosion aboard the bulk carrier W Sapphire Monday evening forced the closure of the Fort McHenry Federal Channel for nearly a full day, creating a backlog of ships before reopening.

Officials have reopened the channel connecting the Port of Baltimore to the Atlantic Ocean after closing it to protect vessels from a hatch cover that blew off a bulker in an explosion. The Port of Baltimore said on Tuesday afternoon that the Fort McHenry Federal Channel had been reopened.

Baltimore County Police have deployed their Fire & Explosion Investigation team after a patrol cruiser was set fire overnight Tuesday in Parkville.

An explosion aboard a massive coal ship in Baltimore Harbor has shut down the Fort McHenry Federal Channel, the same stretch of water where the Key Bridge collapsed earlier this year, officials said.

A ship caught fire in the Patapsco River on Monday, according to the Baltimore City Fire Department. Officials said an under-deck fire caused smoke to billow into the air. It has not been confirmed as an explosion. There are no reported injures.
