WILMINGTON (AP) — Officials say a fire has broken out at an oil refinery in the harbor area of Los Angeles.

City fire spokesman Brian Humphrey says a leak in an 800-pound hydrogen tank at the ConocoPhillips Wilmington Refinery led to the Sunday morning fire.

Fire officials call the blaze small, but a plume of smoke can be seen rising above the refinery from nearby Interstate 110.

Humphrey says the on-site fire brigade is keeping it under control, with city firefighters poised to join them if it grows.

There have been no injuries or evacuations.
