Firefighting crews took advantage of calmer weather Sunday to increase containment of a small wildfire in Oakland, California, that burned two homes.

At least two homes were destroyed by a wildfire in the hills around Oakland, Calif., with the blaze only 50% contained Saturday, local officials said.

A 13-acre vegetation fire damaged homes outside Oakland, local firefighters said on Friday. The cause of the fire has yet to be determined, but during the firefighting efforts, parts of Interstate 580 had to be shut down.
