The U.S.-led military forces in Afghanistan say more than a dozen militants were killed in a day-long battle in southern part of the country Saturday.

A coalition and an Afghan soldier were also killed in the fighting.

Saturday's fighting took place in southern Helmand province. Coalition and Afghan forces called for air strikes on militant positions after coming under attack in the area.

Also in the south, Taleban militants executed the kidnapped son of a district police chief. The victim was reported to be between 14 and 18-years-old.

In other violence, a roadside bomb hit an Afghan army convoy killing at least two soldiers and wounding three others in the western Farah province on Sunday.

A Taleban spokesperson has taken responsibility for the deadly blast.
