Bombings in China's Muslim populated far northwest on Sunday were likely not related to the Olympics and would have no impact on the Games, event organisers said.
Security forces shot dead five attackers who bombed a police station and a government building in the early hours of Sunday morning in a town in Xinjiang region that borders central Asia, Chinese state media reported.
Two policemen and a security guard were reportedly injured in the attacks.
"I do not believe this will have an impact on the Olympic Games... I do not think it is related to the Olympics," Wang Wei, vice president of the organising committee for the Games, told reporters in Beijing.
