Eleven sailors have been injured after an explosion caused a fire on a military ship in San Diego, the fire department said.
The sailors were taken from the USS Bonhomme Richard to hospital with “minor injuries” on Sunday morning, the San Diego Fire Department confirmed.
It added that they were were being treated “for a variety of injuries”.
Video footage showed firefighters rushing into thick smoke billowing from the 257m (844ft) amphibious assault ship docked at the San Diego naval base.
All sailors are believed to be accounted for and have cleared the area.
Emergency crews in boats were spraying the burning ship down with water from hoses.
Federal Fire called on San Diego Fire Rescue crews to respond to the three-alarm fire that started at about 9am local time (5pm BST).
At about midday local time (8pm BST), the fire department said all its personnel had been instructed to leave the pier, as aerial footage showed the fire appearing to grow.
The cause of the fire was not immediately apparent.
The Bonhomme Richard has been stationed in San Diego since 2018 after it spent six years in Japan as part of the US Forward Deployed Naval Force.
