Separately, two top officials faced probe for lapses over a recent daring bomb attack on ruling Communist Party's office.
Three alleged members of the East Turkistan Islamic Movement, a separatist outfit, wanted in connection with a terror attack on April 22, 2015, were killed by police yesterday for resisting arrest, local official media reported.
State-run Tianshan network reported that the three were killed by authorities yesterday for resisting arrest.
On December 28, suspected militants of the East Turkistan Islamic Movement (ETIM), an al-Qaeda affiliated outfit, stormed Moyu government compound in western Xinjiang and detonated self-made bombs, killing an official and a security guard. Three attackers were shot dead at the scene.
After the incident, the provincial government in Xinjiang is stepping up their anti-terrorism efforts and has held officials accountable, state-run Global Times reported.
Zhang Jinbiao, secretary of the Communist Party of China's Hotan prefecture committee, which oversees Moyu county, was also sacked and faced investigation for the same charge.
Although the official announcement stopped short of mentioning the terrorist attack, the daily's report said the action against the officials is clearly related to their "failure in fulfilling their security responsibility".
Chen Quanguo, Party chief of Xinjiang, said at a government video conference on Saturday, that maintaining stability is a major task for all levels of Xinjiang government and this priority overrides all other work.
Chen also called on party members and civil servants in the region to have a clear understanding of Xinjiang's anti-terrorism situation.

Chen called for a thorough crackdown on terrorism and strengthened efforts to improve ethnic ties.
He urged cultivation and protection of patriotic religious personnel and a crackdown on illegal religious activities. He also called for stricter border control and Internet security maintenance.
In 2015, a group of terrorists raided a coal mine in Baicheng, Aksu prefecture, in which 11 civilians and five police officers were killed and 18 others injured.
