All crew members have been evacuated from a burning ship at San Pedro port after a fire caused an explosion that disrupted power and crane operations, the Los Angeles Fire Department said.

Around 8.27pm, or 12.27 pm Hong Kong time, all remaining crew members were assisted off the vessel, bringing the total to 23 safely evacuated with no injuries reported, LAFD said. Six crew members had been previously unaccounted for.

Hazardous materials have been identified in several bays at the port, and firefighters are wearing protective gear and using self-contained breathing equipment.

"First responders are on the scene with more than 100 firefighters working to suppress the fire and Port Police are working to assist the crew to safety," Los Angeles mayor Karen Bass said in a post on X.

A shelter in place order is in effect for communities surrounding the port of Angeles, including San Pedro and Wilmington, she said, adding that the fire department was monitoring air quality as fire suppression continues.

Marine units continue cooling the ship's exterior, with no personnel allowed below deck, the department said. (Reuters)
