The US has stepped up drone strikes in recent days despite strong opposition by the Pakistani Government.
Pakistan's Prime Minister Yusuf Raza Gilani said on Saturday that no permission had been granted to the United States to launch drone attacks on targets inside Pakistan.
"Gilani, who was in Australia, for the Commonwealth Heads of Government Meeting (CHOGM), told a group of Pakistani expatriates said that the rone attacks were counter-productive because they caused collateral damage and undermined the government's efforts to garner support against extremists and terrorists.
He said the drone attacks were one of the reasons why relations between Pakistan and the US had deteriorated in recent months.
Hundreds of tribesmen staged a rally in Islamabad on Friday and called for immediate halt to the American drone strikes in the tribal regions. They said that innocent people are killed in the strikes.
