Authorities Investigating Cargo Ship Explosion In Baltimore

2 weeks ago Authorities are investigating the cause of an explosion aboard a cargo ship that was leaving the Port of Baltimore when it issued a mayday call. Officials say no injuries were reported. The ship W-Sapphire was transporting coal en route to East Africa when the explosion occurred near the site of last year’s Francis Scott Key Bridge collapse. The Port of Baltimore’s main shipping channel was closed Tuesday morning after the Coast Guard established a safety zone around the incident site. Officials didn't provide a timeline for when the channel was expected to reopen.
