Firefighters are at the scene of a two-alarm residential fire in San Francisco's Presidio Heights neighborhood Tuesday afternoon.
The fire is burning in the 300 block of Walnut Street, between Sacramento and Clay streets. Fire department spokeswoman Mindy Talmadge said two buildings are involved in the blaze, and that the fire has crept up into the attic area of at least one building. She said firefighters are opening up the roof to ventilate the fire.
No injuries have been reported, she said.
