China says it has arrested more terror suspects after clash in western region killed 21

Chinese state media say police have arrested more suspects in connection with a clash between authorities and assailants that left 21 dead in the western region of Xinjiang.

Eight suspects already were in custody following last Tuesday's clash, which killed 15 police officers and local government officials. Six of the assailants were killed. Authorities described the gang as terrorists.

China Central Television reported Monday that additional suspects had been captured and interrogated, though it didn't say how many. It also said explosives were seized. The report quoted the state anti-terrorist office and Meng Hongwei, the vice public security minister.

CCTV broadcast images of a memorial service for the 12 men and three women police officers and officials killed in the clash.
