Nine Afghan police were killed in an insurgent attack in the southern province of Uruzgan late Tuesday.

The attack - that authorities said it has been facilitated by a fellow officer and suspected Taliban infiltrator - follows a wave of incidents in recent weeks in which members of the Afghan security forces have turned their weapons on their NATO and US allies.

In the details of Uruzgan incident, the rebels broke into the police post and opened fire on nine sleeping officers, killing all of them, local CID chief Gulab Khan told media sources.

“Nine police are dead. There were 10 people in the post, we believe one of the police led the Taliban into the post and while everybody was sleeping they opened fire and killed nine police," he said.

"The 10th person has disappeared and he's believed to have gone with the Taliban after the killings," Khan added.

The militant group, Taliban, claimed the attack, but the group's spokesman, Yusuf Ahmadi, said the officers were captured and later executed.

The Taliban operations mostly focus on committing suicide attacks and planting IEDs (Improvised Explosive Devices). On Thursday, a roadside bomb blast wounded seven policemen and four other civilians in the eastern city of Jalalabad, official sources said.
