KABUL, May 12 (Xinhua) -- At least 13 Taliban militants were killed after clashes erupted between police and militants in Afghanistan's southern province of Kandahar on Saturday, Ministry of Interior Affairs said Sunday.

"Afghan National Police came in contact with militants in Nadir Khan village, Maruf district, Kandahar province; the clashes left 13 militants dead and nine others wounded," the ministry said in a statement.

There were no casualties on the side of national police, the statement added.

Fighting rages across the war-torn country and clashes between security forces and Taliban have been continuing in at least 25 out of the country's 34 provinces since early April when Taliban launched a yearly rebel offensive.

The militant group has not made a comment on the report so far.
