"Some flags of the 'East Turkestan' forces were discovered at the site, according to the initial findings of the police. Investigation of the terrorist attack is still under way," Foreign Ministry spokesman Qin Gang said.
The "East Turkestan" forces, among which the East Turkistan Islamic Movement (ETIM) is a major group, are one of the major and direct reasons for increasing terrorist attacks in China, particularly in Xinjiang Uygur Autonomous Region, according to state-run Xinhua news agency.
