MOBILE, Ala. (AP) -- A crew that was cleaning fuel barges in Mobile Bay likely caused a spark the triggered an explosion and critically burned three workers.
The explosion happened Wednesday night and it was extinguished Thursday morning.
Coast Guard Lt. Mike Clausen says the investigation is continuing, but the spark from cleaning the barges likely caused it.
The explosion forced the evacuation of workers from the Carnival Triumph cruise ship across the river. The ship has been docked there for repairs since it broke down in the Gulf of Mexico in February and had to be towed back to port.
