Islamabad - Pakistan's Prime Minister Yousaf Raza Gilani said on Thursday that the US has been notified that it cannot continue to carry out aerial strikes on its territory, a day after a US attack killed six people near the border with Afghanistan.

"The US government has been clearly told that there would be no compromise on the sovereignty and territorial integrity of Pakistan," he said during a meeting with the ministers of North West Frontier Province (NWFP) in Islamabad.

Multiple missile strikes carried out by US drone aircraft in the Baghar Cheena village of South Waziristan tribal district along Afghan border killed at least six people, including three Taliban and an alleged al-Qaeda operative late Wednesday.

The attack came shortly after Admiral Mike Mullen, chairman of the US Joint Chiefs of Staff Committee, met Pakistani leaders, including premier Gilani and army chief Ishfaq Parvez Kayani during his unannounced visit and reaffirmed "the US commitment to respect Pakistan's sovereignty."

Media reports cited Pentagon officials as saying that Pakistani authorities had been informed that US predators were being deployed to destroy an ammunition dump in South Waziristan.

But Pakistani Foreign Minister Shah Mahmood Qureshi categorically denied that. "No Sir! We were not informed," he told journalists in Islamabad on Thursday.

"That means there is some sort of an institutional disconnect on their (Americans) side and, if so, they have to sort it out," Qureshi added.

Gilani said Pakistan would not allow any foreign forces to hit targets on its soil because "such strikes prove counter productive."

He emphasized the need for "greater intelligence sharing and better coordination" between the forces of Pakistan and those of the US, NATO and ISAF deployed in Afghanistan.

Relations between Islamabad and Washington, the two key allies in the fight against terrorism in Afghanistan have been strained by a upsurge in US attacks inside Pakistan's tribal areas which are considered a safe haven for al-Qaeda and Taliban militants.

After assessments by top US military officers that the Americans were not winning the war against the Taliban, the United States is seemingly revising its security strategy in Afghanistan and along the frontier.

Islamabad has said it was doing all it could do to eliminate Taliban and al-Qaeda sanctuaries in the treacherous mountain region, but insists that US attacks would fuel anger towards Americans and increase sympathy for militants in the country. (dpa)
