Attacks by US drones on Pakistani territory are "counter-productive" because they undermine Islamabad's efforts to isolate militants, Yousuf Raza Gilani, Pakistan prime minister, says.
Mr Gilani's comments at the weekend came as Pakistan stepped up its efforts to regain control of the northern Swat valley from Taliban militants. The military launched a campaign to seize Mingora, the main administrative and commercial hub of the region.
