LOS ANGELES (AP) — A fire has broken out aboard a container ship in Los Angeles, prompting emergency services to take extensive measures to protect surrounding communities. The fire, which began Friday night on the One Henry Hudson, has persisted into Saturday morning, leading authorities to issue a shelter-in-place order for nearby areas including San Pedro and Wilmington due to concerns about hazardous materials onboard.

The Los Angeles Fire Department confirmed that all 23 crew members have been accounted for and are safe, with no reported injuries from what officials have described as an electrical fire. Mayor Karen Bass urged local residents to remain indoors, keeping windows closed and HVAC systems off.

In response to the incident, the U.S. Coast Guard has established a safety zone extending one nautical mile around the vessel. Firefighters are working tirelessly—more than 100 have been deployed to control the blaze, which reportedly started below deck before reaching several levels of the ship and resulting in a mid-deck explosion.

As firefighters combat the flames, the threat posed by the hazardous materials aboard the One Henry Hudson remains a significant concern. The vessel is approximately 1,102 feet long and is operated by One Ocean Express, which has its headquarters in Singapore. It made prior stops in Japan before arriving in Los Angeles.

As emergency services continue their firefighting efforts, local authorities are monitoring the situation closely and providing updates to the community.
