Beijing- At least six people have been injured in a knife attack at a station in Guangzhou, Chinese officials said today. Police shot one of the attackers, a statement from the city's public security bureau said. There is no information yet on the motivation for this attack, but it comes a week after an attack on a station in Urumqi, in the western region in Xinjiang. It also follows an attack at Kunming station in March that killed 29 people. Chinese authorities have blamed both these attacks on separatists from the Muslim Uighur minority group, which lives in Xinjiang. An image posted by the People's Daily showed crowds evacuated from the station and an ambulance at the scene. In a statement on the public security bureau's official microblog, police said they arrived at the station at 11:30 today. They shot a male suspect armed with a knife after he failed to heed warnings, they said. The six injured people had been taken to hospital for further treatment they said, and further investigations were underway.
