One person has died after a fire and two explosions Friday at a New York City shipyard, officials say.

Axar.az informs, citing Times Colonist, that 36 people were injured, most of them firefighters and other first responders, and one civilian died at the scene.

A firefighter and a fire marshal were inside the structure when a second explosion happened, and both were seriously injured by the shock wave from the blast.

“This was a complex, fast-developing emergency situation,” New York Mayor Zohran Mamdani said during a news conference Friday evening.

Multiple people called the fire department around 3:30 p.m., reporting smoke and two workers trapped in the basement of a 150-foot by 150-foot (46 meters by 46 meters) metal structure at the back of the shipyard, Fire Commissioner Lillian Bonsignore said.
