BEIJING - Three people were condemned to death Friday and one given life in prison for a mass stabbing that killed 31 people in China, state television said, an attack authorities blamed on separatists from largely Muslim Xinjiang.
The convictions and sentences were handed down by the Intermediate People's Court in Kunming, in the southwestern province of Yunnan, state broadcaster China Central Television (CCTV) reported on a verified microblog.
The March 1 carnage at a train station in Kunming also saw more than 140 people wounded and was dubbed "China's 9/11" by state-run media.
The suspects, whose names appear to identify them as members of the Uighur minority, had been accused of crimes including "leading a terrorist group" which planned and carried out the attack, Kunming's Intermediate Court said earlier on its microblog.
Four armed guards in helmets and dark clothing, and holding automatic weapons, were positioned inside the courtroom opposite the suspects, CCTV showed.
The accused -- three of them men with shaved heads, the other one a woman -- wore prison clothes. Each of them had a separate dock, with two police officers sitting behind.
State prosecutors said three of the suspects -- whose names were transliterated as Iskandar Ehet, Turgun Tohtunyaz and Hasayn Muhammad by the official news agency Xinhua -- were arrested while attempting to cross China's border, according to the court.
The other accused, named as Patigul Tohti, took part in the attack, along with at least four other assailants whom police shot dead at the scene, prosecutors added.
Authorities had previously given the toll as 29, but the change indicated that two of the wounded had later died of their injuries.
More than 300 members of the public were present in court, Xinhua said, including some victims and their relatives.
Beijing blamed the attack on "separatists" from the resource-rich far western region of Xinjiang, where at least 200 have died in attacks and clashes between locals and security forces over the last year.
Militants from Xinjiang were accused of organising an explosive attack in the regional capital Urumqi which killed 31 people in May, and a suicide car crash in Beijing's Tiananmen Square last year.
The Kunming mass knifing was the biggest-ever violent incident against civilians outside the region.
