YEREVAN, MARCH 27, ARMENPRESS. Six people, who were believed to be part of a road construction crew, are presumed dead after Baltimore's Francis Scott Key Bridge collapsed early Tuesday morning, CNN reports.

The collapse came after the Singapore-flagged container vessel Dali hit the bridge's pillar. Eight people were on the bridge when it fell, according to officials. At least two people were rescued. Some of the individuals missing after the collapse of the bridge are Mexican nationals. 2 of them are from Guatemala, the country's foreign ministry said.

As the odds of their survival vanished, the search for the six workers was suspended on Tuesday evening, 18 hours after they were thrown from the fallen Francis Scott Key Bridge into the frigid waters at the mouth of the Patapsco River, Reuters reports.

Maryland State Police and U.S. Coast Guard officials said diminished visibility and increasingly treacherous currents in the wreckage-strewn channel made continued search efforts on the river too risky to continue overnight.

Starting at 6 a.m. (1000 GMT) on Wednesday, "we're hoping to put divers in the water and begin a more detailed search to do our very best to recover those six missing people," state police Colonel Roland Butler told reporters late on Tuesday.

Maryland's governor Wes Moore said the crew on the ship was able to issue a “mayday” call before colliding with the bridge, which allowed authorities to stop incoming traffic and likely saved lives.
