Tibetan Freedom Riders in Gansu (from youtube)

Tibetan rioters spilled into the neighbouring Chinese province of Gansu Tuesday and tried to storm a government office, despite efforts by the military to quell protests against Chinese rule.
Roughly 100 armed troops holed up inside the building repelled the protesters with tear gas, as CTV cameras (Canadian TV) filmed the confrontation.
One protester, bleeding profusely from the head, said he had been beaten by the soldiers.
The crowd then moved to a school in the remote town, located close to the Tibetan border, where they pulled down the Chinese flag and replaced it was the former national flag of Tibet.
