Three protesters have scaled San Francisco's famous Golden Gate Bridge, just as the Olympic torch is due to arrive in the city.
The protesters draped the Tibetan flag and banners from the landmark, to show support for Tibet's claims for independence from China, which is to host this year's Games. This is the latest in a series of demonstrations which have disrupted the Olympic torch's journey around the world. Despite the protests, Chinese officials say the relay has enjoyed huge support from local governments and Olympic Committees.
