China has executed eight people for "terrorist" attacks in its restive far western region of Xinjiang, including three who "masterminded" a dramatic car crash in the capital's Tiananmen Square in 2013, state media said.
Xinjiang is the traditional home of Muslim Uighurs who speak a Turkic language, and China has attributed attacks there to Islamist separatists it says seek to establish an independent state called East Turkestan.
Exiled Uighur groups and human rights activists say the government's own repressive policies in Xinjiang have provoked unrest, an accusation Beijing denies.
