According to official sources at least seven militants were killed in an offensive by security forces on Sunday as they pounded the hideouts of militants in upper Orakzai, a private TV reported. Security forces have targeted suspected hideouts of the slain outlawed TTP commander Hakeemullah Mehsud. So far troops claim to have destroyed at least three militant hideouts. At least ten militants were killed and three of their hideouts also ruined during airstrikes in Upper Orakzai Agency on Saturday. The recent surge follows reports that members of the top leadership of Al Qaeda and TTP have shifted to Orakzai from Waziristan and Swat.
