According to Chinese government sources, it was a terrorist attack perpetrated by two men with suspected ties to the Uyghur separatist movement. The men reportedly drove a truck into a group of approximately 70 jogging police officers, and proceeded to attack them with grenades and machetes, resulting in the death of sixteen officers. Foreign tourists who witnessed the scene provided a divergent account of events, saying that the attackers appeared to be machete-wielding paramilitary officers.[1]
