On 27 May 2014 a rare mass trial was held at a packed sports stadium in Xinjiang where three people were sentenced to death and another 53 received lengthy jail terms, after being convicted of terrorism charges. 39 people had been sentenced at a similar gathering a week previous. An anti-terror campaign which began in 2013 and continued into 2014 preceded the sentencing trials. The campaign included attacks on railway stations and a market in Xinjiang in which seventy people were killed and several hundred wounded.
