Afghan police say Taliban militants attacked a police patrol in southern Helmand province overnight Saturday, killing four officers and wounding seven others.

The local police commander, Khair Mohammad Shuja, said the attack took place in the Gereshk district and that his forces detained wounded Taliban at the scene early Sunday.

News reports say two additional attacks took place in Afghanistan Sunday resulting in more police and civilian deaths but details are still emerging about those incidents.
