Pakistan says US drone attacks must end
The US delegation is led by Senator John McCain, the former presidential candidate.
Gilani said his government was "disappointment over the continuing drone attacks" and criticized Washington for not sharing pilotless drone technology with Islamabad, Pakistan's official APP news agency reported Saturday.
Pakistan says it can fight militants operating in its border areas better if it has the know-how.
Senator McCain, who led the US delegation, defended the drone strikes, saying they are "one of many tools that we must use to try to defeat a very determined and terrible enemy."
US officials say the drone strikes are carried out under an agreement with Islamabad. Pakistan denies any such agreement.
Washington has stepped up its drone strikes in Pakistan since seven CIA agents were killed in neighboring Afghanistan almost ten days ago. At least four people died in the latest missile attack.
Pakistan's opposition parties, meanwhile, have expressed regret over the attacks, asking the government to shoot them down.
In 2009, the attacks, launched by the US Central Intelligence Agency (CIA) in cooperation with the Pentagon, reportedly killed more than 700 civilians in the country.
They have also fueled anti-American sentiments in the Muslim Pakistan.
