All 31 workers have been rescued after an industrial tunnel collapsed in Los Angeles' Wilmington area, city officials said late on Wednesday.

The tunnel that collapsed had a diameter of 18 ft (5.5 m) and was being constructed for municipal wastewater management, the Los Angeles Fire Department (LAFD) said in a statement.

"LAFD has just reported that all workers who were trapped in the tunnel in Wilmington are now out and accounted for. I just spoke with many of the workers who were trapped. Thank you to all of our brave first responders who acted immediately," Los Angeles Mayor Karen Bass said in a post on X.

The collapse happened about six miles (10 km) south of the tunnel's only access, LAFD said, adding that more than 100 responders were assigned to the incident.
