Security has further been beefed up in northwest China's Xinjiang region, a day after militants carried out a terror attack ahead of the Olympics, killing 16 policemen and injuring an equal number of others.
Road checks were intensified in Xinjiang Uygur Autonomous Region and a full security vigilance in public places, including government office buildings, schools and hospitals was ordered, state media reported.
The Uighur separatists on Monday had rammed a truck into a group of Chinese border guards and lobbed grenades when the policemen were jogging outside their barracks in the border city of Kashi, raising security concerns ahead of the game.
Authorities suspected the hand of the banned East Turkistan Islamic Movement behind the attack which they said had plotted terror attacks during August one to eight ahead of the opening ceremony of Olympics.
Authorities in Kashi on Monday reinforced police power at road entries to the city, official Xinhua news agency said.
In Xinjiang's capital Urumqi, special police used devices in routine street patrols which can help trace identity data through the police network and send out alerts if an ID matches with that of a blacklisted suspect at large, it said.
Among a raft of measures, the country has also deployed over one lakh security guards and 300,000 cameras.
A week ago the Uigur group had claimed responsibility for a spate of bombings, including the May five strike in Shanghai which killed three persons and an attack on police in Wenzhou in July, but the Chinese authorities had dismissed them.
