In Tibet, the Chinese threw a bomb at a government building.

Unidentified terrorists threw a bomb at a government building, located in Gantszy-Tibetan autonomous prefecture of Sichuan province, reports Reuters referring to the agency "Xinhua". Data on injuries were reported.
  The Chinese government информагентство reported that the group left the scene for investigators.
Presumably, the attack could be linked to a 50-year anniversary of the uprising in Lhasa, which was brutally suppressed by Chinese authorities. As a result, the Dalai Lama was forced to flee Tibet and to flee to India.
In 2008, the anniversary of the uprising was accompanied by massive protests by the Tibetan population, which degenerated into clashes with police. According to the Chinese authorities killed 21 people, the information of Tibetan government in exile - about 200 people.
In 2009, fearing a repetition of the riots, China has increased the number of troops in Tibet on the border with India and Nepal.
