Islamabad: Pakistan on Saturday summoned US ambassador to the foreign ministry and lodged a formal protest over the drone strike which killed Pakistan Taliban chief Hakimullah Mehsud, the foreign ministry said.
"In order to register our concerns, the US ambassador was called to the foreign office by the foreign secretary to register our protest over the recent drone attacks," Xinhua quoted a foreign ministry statement as saying.
The latest drone strike will have a negative impact on the government's initiative to undertake a dialogue with the Tehrik-e-Taliban Pakistan (TTP), it said.
The government, however, is determined to continue with these efforts to engage with the TTP to bring an end to the ongoing violence and make them a part of mainstream politics within the parameters of the constitution, it said.
