315 PST:

No major incidents have been reported. The route was changed and shortened, and some minor skirmishes in the crowd have been reported.

The torch was lit about 25 minutes behind schedule, then the runners disappeared for more than a half-hour. Police escorted the torch about 2 miles from its original starting point, starting the run away from protesters and supporters gathered on the published route.

Crowds along the original starting point began walking away when the torch failed to appear. Some minor clashes were reported along the route as the crowds waited.

A troop of protesters wielding Tibetan flags crossed the main route and briefly confronted a group waving large Chinese flags. ``You are decades behind civil rights!'' one protester shouted at a supporter in the crowd.

As runners carry the torch on its six-mile route Wednesday, they will compete not only with people protesting China's grip on Tibet and its support for the governments of Myanmar and Sudan, but also with more obscure activists. They include nudists calling for a return to the way the ancient Greek games were played.

Local officials say they support the diversity of viewpoints, but have ramped up security following chaotic protests during the torch's stops in London and Paris and a demonstration Monday in which activists hung banners from the Golden Gate bridge.
