Taliban militants killed four policemen in Kandahar province in southern Afghanistan, provincial police chief Asmatullah Alizai told Xinhua on Saturday.

The militants ambushed a police convoy in Mushan village of Panjwai district on Friday night, killing four policemen and injuring three others, Alizai said.

A police vehicle was damaged in the conflict, he added.

Alizai said it was unknown whether there were casualties on the Taliban side.

Kandahar has been a hotbed of Taliban militants, who clash with foreign and Afghan forces frequently.

Due to rising Taliban-linked violence, over 300 people, mostly Taliban militants, have been killed in Afghanistan this year.
