Three security officers have been stabbed to death and another wounded in renewed violence in China's Xinjiang region.
The attack in China's far northwest comes on the fourth day of the Olympic Games in Beijing.
An assailant jumped off a vehicle passing a road checkpoint about 30km from Kashgar and stabbed the officers, Xinhua news agency said.
China has blamed two earlier attacks in the restive area, more than 3,000km from the capital, on Muslim separatists seeking to disrupt the Games.
Today's attack occurred in the same area where 16 police were killed in a bombing and stabbing attack just over a week ago. Chinese state media has insisted there is no link between the two incidents.
Police are still investigating Sunday's attack in Kuqa, in the south of Xinjiang, where 11 were killed in a series of supermarket bombings.
China claims militants seeking an independent ‘East Turkestan’ homeland for Muslim Uighurs in the region are among the top threats to the Olympics, which began on Friday.
However, the government is reportedly downplaying the attacks in the Chinese press.
According to reports, today’s attack was initially only reported in English by Xinhua .
Xinjiang is home to the majority Muslim Uighur people, who make up just under half of Xinjiang’s 20 million people.
