SAN FRANCISCO (AP) — Fire officials say a gas leak turned into an explosion in a residential San Francisco neighborhood and that nearby buildings are being evacuated. No injuries have been reported.

San Francisco fire officials say the explosion at an apartment building happened Monday morning after an initial report of a gas leak.

Television images show window blinds and glass blown out from the second story of an apartment building into a street in the Bernal Heights neighborhood.

The San Francisco Fire Department says it is working with Pacific Gas and Electric Company on the gas leak.

PG&E did not immediately return a call seeking comment.
