Two individuals have been found deceased inside a submerged red pickup truck following the collapse of the Baltimore bridge.

During the incident, triggered by a collision with a ship, eight construction workers fell into the water below.

Although two workers were rescued promptly, efforts are ongoing to locate the remaining four, who are unfortunately presumed to have perished.

Salvage teams are currently engaged in mitigating hazardous materials, while accident investigators are present at the site.

Out of the six victims of the bridge collapse, the identities of four have been disclosed.

In a recent press briefing on Wednesday, Maryland State Police revealed the names of the two recovered workers: Alejandro Hernandez Fuentes, aged 35, and Dorlian Ronial Castillo Cabrera, aged 26, both of whom were found within the truck. Mr. Fuentes hails from Mexico, while Mr. Cabrera is of Guatemalan origin.

However, due to the presence of concrete and debris obstructing the river, diving operations have been halted for safety reasons. Authorities are now relying on sonar scans, suspecting that other vehicles containing bodies might be trapped beneath the collapsed bridge structure.

Additionally, the identities of two other missing individuals, presumed deceased, have been disclosed: Miguel Luna, originally from El Salvador, and Maynor Suazo Sandoval, a citizen of Honduras.

Mexico's Ministry of Foreign Affairs said earlier that two of its citizens were presumed dead - one of whom is now identified as Mr Fuentes - while another was rescued from the water.

One person who was in hospital after being pulled out of the water was released, officials said late Wednesday.

First responders spent hours on Tuesday searching the waters of the Patapsco River for the six construction workers, who were working on potholes on the bridge around 01:30 (05:30 GMT) when the ship crashed into the bridge.

The US Coast Guard called off the search around sunset, saying cold water temperatures and hours gone by meant the workers were presumed dead.

Officials have pledged to find the bodies of the men for their relatives.

"We've got to give these families closure," Wes Moore, governor of Maryland, told reporters on Wednesday, adding that air, land and water resources had been devoted to the search of the victims.

"My promise to them is this: I will devote every single resource to make sure that you receive closure," he said.

But the operation has been challenging, Coast Guard Vice Admiral Peter Gautier said on Wednesday.

Divers have been swimming in chilly waters with metal debris from the bridge that fell in the river.

The cargo vessel itself is stable but has over 1.5m gallons of fuel oil and lube oil on board, Mr Gautier said.

Roughly 4,700 cargo containers were also on board, including 56 that contained hazardous materials.

"The Coast Guard has moved aggressively to board the vessel, and we have teams on board," Mr Gautier said.

Jennifer Homendy, chair of the National Transportation Safety Board, said some containers with hazardous materials had been "breached".

The US Navy plans to use barges with heavy lift cranes - some can carry as much as 1,000 tonnes - to remove parts of the bridge that fell in the water.

The Dali was headed toward Sri Lanka when it lost power all of a sudden and issued a distress call before crashing into the Baltimore bridge.

A data recorder recovered from the ship shows that power failed for just over a minute, but this was enough to make the collision unavoidable.

In an audio recording, the pilot can be heard giving steering commands and rudder orders as it approaches the bridge.

Officials say the bridge collapse at a key port could pose a risk to global supply chains and the US economy.

Mr Moore said that 8,000 jobs could be affected by the bridge collapse and called the incident a "global crisis".

"The national economy and global economy depends on the port," he said, noting that $80bn (£63.4bn) of cargo moved through there last year.

Paul Wiedefeld, Secretary of the Maryland Department of Transportation, stressed that replacing the bridge will not be a fast process, but he promised at Wednesday's press conference that officials are working to "come up with a design for the replacement of that bridge as quickly as possible to get the port back up and the community back up and running".

Experts say Key Bridge's collapse could lead to losses of up to $15m (£11.8m) per day, until the shipping lane is reopened.

US Senator Ben Cardin of Maryland said he was confident "thanks to the Biden administration" the state would get the necessary resources to recover and begin work on a replacement bridge.

"Our top priority is to get the shipping lane open because of the impact it has on our country and the global supply chain," he said.

Investigators are also hoping to determine whether dirty fuel played a role in the deadly crash. Maritime experts say contaminated fuel can cause a ship to black out as it creates problems with a vessel's main power generators.
