BALTIMORE (Reuters) - Six workers were missing and presumed dead from a bridge that collapsed in Baltimore Harbor early on Tuesday after a massive cargo ship crippled by a power loss rammed into the structure, forcing the closure of one of the busiest ports on the U.S. Eastern Seaboard.

With dive teams facing increasingly treacherous conditions in the darkened, wreckage-strewn waters, active search-and-rescue operations were suspended about 18 hours after the accident, U.S. Coast Guard and Maryland State Police officials said.
