PAKISTANS military officials are mulling over carrying out an offensive against the militants and fleeing insurgents in the North Waziristan Agency (NWA), an American TV channel has claimed. Citing deep-rooted sources in Pakistan Army, the channel also claimed that the said operation might take as less as six months to commence. The recent drone strikes were aimed at targeting insurgents that have fled towards northern tribal areas, it added. A Pakistan army official told the US channel that the number of escaping insurgents was on a rise in North Waziristan, and according to him, the fleeing insurgents were taking shelter in Tirah Valley. Three US drone attacks also took place in Tirah Valley of Khyber Agency on Friday, which killed 57 Taliban, he added. He also told the channel that the Pakistan Army was planning to launch a military offensive in North Waziristan, as insurgents were using the agency as 'safe havens and 'protected sanctuaries to plot and carry out attacks inside Afghanistan. The insurgents hiding in the NWA have launched several terror strikes in Pakistan as well, the army official further said. Pakistan wants more control over the drone programme, as this could help save precious lives of common men in tribal areas, the Army official argued.
