Afghan officials say Taliban militants killed 11 policemen late Sunday, while two NATO soldiers died in a separate incident in the southern Afghan province of Kandahar.

The local deputy police chief, Amanullah Khan, says Taliban militants opened fire on a group of sleeping policemen at a remote checkpoint in Kandahar's Arghandab district.

He said preliminary reports indicate that one of the policemen had links with the Taliban.

Meanwhile, the British Defense Ministry confirmed that two Royal Air Force servicemen were killed when their vehicle hit an explosive device.

NATO's International Security Assistance Force says two other British soldiers were wounded in the blast Sunday. The ISAF did not disclose the exact location of the incident.

The Taliban ambush was the latest in a series of recent attacks on Afghan police in the south. Eight police officers were killed Saturday in Kandahar and neighboring Helmand Provinces by the militant group.
