Chinese police investigating a spate of attacks this month in western Xinjiang province shot dead six suspects and arrested three others, state media reported. An exile group, meanwhile, accused police Saturday of gunning down the suspects, members of the Muslim Uighur ethnic minority, after they surrendered. Police encountered nine suspects in a corn field near the far western city of Kashgar on Friday evening, the official Xinhua News Agency reported. The suspects had knives and tried to resist arrest, putting up a "desperate struggle," it said late Friday. A policeman and a local militia man were wounded in the clash, the report said. Initial investigations linked the suspects to attacks on Aug. 12 and Aug. 27, Xinhua said. The report gave no other details.
