AP has a few more details on the bomb thrown at a police station in Ganzi, a Tibetan region of Sichuan. The station was apparently unoccupied at the time:
The explosion shattered windows at the newly built station in Bogexi, a town in the predominantly Tibetan Ganzi prefecture, police official Liu Xiaojun said Tuesday.
The building was not yet occupied at the time of the blast early Monday and an investigation was under way, said Liu, who works at the public security bureau in Batang county, which oversees the town. Batang, in Sichuan province’s far west, is about five miles (seven kilometers) from the Tibetan border.
Bombings have previously occurred in Tibetan areas, and Beijing has portrayed them as part of a campaign of violence by the Dalai Lama and his supporters to overthrow Chinese rule, although authorities have provided little evidence to support the allegation.
