KANDAHAR: Seven people were killed Tuesday in two separate ambushes in southern Afghanistan in the wake of parliamentary polls, officials said. The first attack was at 10am in the Gizab district when Taliban rebels attacked the district police chief Haji Said, wounding him and killing his three colleagues. Three police and one Taliban were also killed in the fighting. Three Taliban were killed after a group of rebels attacked a police patrol in neighbouring Zabul province's Mizan district on Tuesday.
