At least three policemen were killed Sunday in an attack in north-western Pakistan, security officials said.
The attack took place in Shangla district where security forces launched a major offensive in early 2009, DPA reported.
Local police official Dilawar Khan said several dozen attackers raided a check post in the early morning in the Alpori area.
"They fired at the policemen with rockets and assault rifles," Khan said. "Three policemen were killed and one was injured. The attackers fled after the raid."
Pakistani forces had claimed that Taliban insurgents were expelled from Shangla and nearby districts in 2009 but rebels continue attacks on civilians and government officials from mountain hideouts.
