There is frequent unrest in west China, between authorities and Muslim minority ethnic Uighurs.

The attackers had used bombs and knives to launch their offensive at the police officers at the checkpoint، after speeding through it. Some speculate that one possible motive behind the assault could be tighter restrictions on the Uighurs by Chinese state over the month of Ramadan.
Muslim party members، civil servants and students are barred from observing the holy practice while other Muslims fast during Ramadan.
