According to detailed accounts, on 13 May 2005, some 400 of the 500 protesters staging an anti-government demonstration were killed after being driven deliberately into a trap – authorities had blocked all the exits from Bobur Square with armoured personnel carriers, preventing people from dispersing home. Instead, they drove the crowd into a closed street, Chulpon Avenue, where snipers and police shot to kill. These scenes of deliberate killings prompted eyewitnesses to allege that troops not only shot to disperse the demonstration, but to summarily execute anyone who took part in it. Later, some tortured detainees recounted that police said they had received orders supposedly emanating from the president himself to shoot to kill.
