BEIJING, Aug. 10 (Xinhua) -- Organizers of the Beijing Olympic Games slammed the serial bombings in the northwestern Xinjiang Ugyur Autonomous Region on Sunday, saying they were aimed at seceding China but are not to impact the Beijing Games.

    East Turkistan separatist forces never stopped their secessionist activities in Xinjiang, said Wang Wei, spokesman with the Beijing Organizing Committee of the 29th Olympic Games. "Such activities are not allowed in any country."

    "It's possible they intended to use the Beijing Games as a platform to amplify the effects of their secessionist activities," Wang said at a press conference jointed held by the BOCOG and the International Olympic Committee, "but the primary motive was to secede."

    He said terrorist activities had existed in Xinjiang for "some time" and the recent attacks were not immediately related to the Beijing Games.

    "I don't think these will have any impact on the Beijing Olympics. But of course, we'll further tighten security in the region," the spokesman added.

    Several bombings that occurred in Kuqa County of southern Xinjiang at around 2:30 a.m. injured two police officers and a security guard, according to the regional public security department.

    Witnesses saw that some people hurled home-made explosives from inside a taxi, attacking the local public security station and industrial and commercial office.

    In the accident, two police officers and a security guard were injured, and two police cars were destroyed. Police reportedly killed five attackers at the scene.

    Local security has been tightened and an investigation is underway.

    Kuqa has a population of 400,000. It is about 740 kilometers from Urumqi, the regional capital.
