Firefighters battle four-alarm fire at San Francisco's Pier 29
A four-alarm fire broke out Wednesday afternoon in an empty two-story building on Pier 29 in San Francisco, officials said.
The fire began just before 2 p.m. in the 1300 block of Embarcadero. The building was under construction to house the America's Cup, a yacht race scheduled in 2013. No injuries have been reported so far.
Photos from Twitter show thick smoke and large flames coming up from the building. Firefighters attacked the fire with hoses on both sides, before the roof collapsed.
The Embarcadero has been blocked off from Sansome Street to Bay Street, San Francisco police Officer Wilson Ng told the San Francisco Chronicle.
