A group on the United Nations' terrorist list was confirmed to have masterminded a deadly incident in the Xinjiang Uygur autonomous region last month.

The East Turkistan Islamic Movement was identified as orchestrating the attack in Xinjiang's capital Urumqi on April 30, killing three and injuring 79, the provincial publicity department said on Sunday.

ETIM member Ismail Yusup, who lives outside China, planned the incident, it said, and on April 22 ordered 10 associates to launch the attack. Eight days later, the gang set off explosives and slashed people with knives at the exit of the South Railway Station of Urumqi around 7:10 pm.
