SAN FRANCISCO (AP) - Police say 19 people were hurt including five critically when an open-air tour bus crashed in San Francisco's Union Square.
Officials say there may have been as many as 30 people aboard the bus.
KRON-TV producer Shannon Adams says she saw the double-decker bus careening down the street at high speed before it hit several cars and smashed into scaffolding at a construction site.
Fire officials say power lines are down in the area.
