Firefighters extinguished a blaze at the Port of Long Beach complex Sunday evening that began in a tree and spread to a boat and nearby building, officials said.

The fire was put out in about 20 minutes, but left hazy air and the smell of smoke in the Downtown area.

It’s not clear how the initial fire started.

Firefighters responded at about 6:30 p.m. in the 1500 block of Pier C Street, just west of the Los Angeles River and 710 Freeway.

No injuries were reported, said Capt. Jack Crabtree, spokesman for the Long Beach Fire Department.

Multiple trees burned, a building and a boat that was not in water but was housed near the building, Crabtree said.
