Search for survivors suspended

Officials say they are transitioning from search and rescue operation to a recovery operation.

US Coast Guard and Maryland State Police officials say that based on the frigid temperature of the water and the length of time that had elapsed since the bridge came down there was little if any chance that the six missing could be found alive.

First responders' heroism is 'ray of light', says senator

Maryland's senator has praised the work of first responders, saying their heroism is a "ray of light on this dark day". 

Emergency workers managed to stop traffic along the Francis Scott Key Bridge after the Dali container ship put out a mayday call.

Chris Van Hollen said their actions "saved lives" and he was "thankful for them". 

A team of construction workers were repairing potholes along the bridge at the time it collapsed. 

Eight people were initially reported missing, but two people were found, with one suffering serious injuries. 

A short while ago, we heard from the executive vice president of construction company Brawner Builders, who confirmed the six workers still unaccounted for are presumed dead.

Six workers presumed dead, says company official

Six workers missing after the Baltimore bridge collapsed are presumed dead, the executive vice president of Brawner Builders has confirmed. 

Jeffrey Pritzker told our US partner site NBC News that there was one survivor. 

The company is not releasing names at this time.

Eight people, who were working on the bridge at the time it was struck by the Dali cargo ship, were initially reported missing. 

Two of them were found, with one suffering serious injuries. 

The other six have been missing for more than 12 hours. 

Emergency operations centre 'fully staffed'

Maryland's emergency management department has raised its state activation level. 

It is now registered as 'full' - meaning an incident has occurred that may require significant resources. 

As a result, the state's emergency operations centre has been "fully staffed". 

The state's activation levels change based on a variety of factors.

The most influential factor is the occurrence of a significant incident, which is a term used to describe a single or multi-jurisdictional incident. 

Construction workers were on a break when ship hit bridge, says colleague

A construction worker has said he was told his missing colleagues were on a break when the Dali ship crashed into the Baltimore bridge. 

Jesus Campos told the AP news agency some members of staff were sitting in their trucks when the bridge collapsed. 

The Brawner Builders employee said he learned about the disaster from a co-worker and immediately worried about colleagues he knew were working on the bridge. 

"When he told me that, they came to mind and I was praying to God that nothing had happened to them," he added.

"It is so hard for me to describe. I know that a month ago I was there, and I know what it feels like when the trailers pass.

"Imagine knowing that it is falling. It is so hard, one would not know what to do," he said. 

Person injured in bridge collapse discharged from hospital

One person involved in the Baltimore bridge collapse has been discharged from hospital, an official at the R Adams Cowley Shock Trauma Centre has told AP. 

Dr David Efron did not comment on the nature of the patient's injuries, and the hospital has not released their name. 

Eight people were initially reported missing after the collapse. 

Two people have been found - one was said to have serious injuries, while the other did not require hospital treatment. 

Search and rescue operations are continuing this evening to find the six construction workers still missing. 

Bridge is a 'cathedral of American infrastructure'

The US transportation secretary has said the path to rebuilding the collapsed Baltimore bridge will not be quick or easy. 

Pete Buttigieg described the bridge as "one of the cathedrals of American infrastructure". 

"It has been part of the skyline for this region for longer than many of us have been alive," he said.

He has also taken the time to thank first responders and offered comfort to those "who woke up today to the news that no one wants to receive". 

"This is an excruciating day for several families," he said. 

Aerial images capture moment of impact

Clearer satellite images have emerged of the moment the Dali container ship hit the Francis Scott Key Bridge.

The vessel crashed into the structure after issuing a mayday call and losing power.

Earlier, Maryland governor Wes Moore said the ship was travelling at a speed of eight knots at the time it sent out its distress call.
