PESHAWAR, Pakistan (Reuters) - A U.S. drone strike killed the number two of the Pakistan Taliban in the North Waziristan region on Wednesday, three security officials said, in what would be a major blow in the fight against militancy.
The drone strike killed seven people, the Pakistani security officials said, including Taliban deputy commander Wali-ur-Rehman, in the first such attack since a May 11 general election in which the use of the unmanned aircraft was a major issue.
Wali-ur-Rehman had been poised to succeed Hakimullah Mehsud as leader of the Pakistan Taliban, a senior army official based in South Waziristan, said in December.
"This is a huge blow to militants and a win in the fight against insurgents," one security official told Reuters, declining further comment.
The Pakistani Taliban are a separate entity allied to the Afghan Taliban. Known as the Tehreek-e-Taliban Pakistan (TTP), they have launched devastating attacks against the Pakistani military and civilians.
Drone casualties are difficult to verify. Foreign journalists must have permission from the military to visit the Pashtun tribal areas along the Afghan border.
Taliban fighters also often seal off the sites of drone strikes immediately so Pakistani journalists cannot see the victims.
The Pakistani Taliban were not immediately available for comment.
The security officials and Pashtun tribesmen in the northwestern region said the drone fired two missiles that struck a mud-built house at Chashma village, 3 km (2 miles) east of Miranshah, the region's administrative town.
They said seven people were killed and four wounded.
"Tribesmen started rescue work an hour after the attack and recovered seven bodies," said resident Bashir Dawar. "The bodies were badly damaged and beyond recognition."
The Pakistan government had yet to confirm Wali-ur-Rehman's death. A U.S. drone killed Pakistani Taliban commander Baitullah Mehsud in 2009.
U.S. President Barack Obama recently indicated he was scaling back the drone strike program, winning cautious approval from Pakistan, a key ally in the U.S. fight on militancy.
A Pakistani Foreign Ministry official, speaking before the identity of the Taliban number two had been revealed, condemned all such strikes.
"Any drone strike is against the territorial integrity and sovereignty of Pakistan and we condemn it," the official, who declined to be identified, told Reuters.
North Waziristan is on the Afghan border and has long been a stronghold of militants including Afghan Taliban and their al Qaeda and Pakistani Taliban allies.
Prime Minister-elect Nawaz Sharif said this month that drone strikes were a "challenge" to Pakistan's sovereignty.
"We will sit with our American friends and talk to them about this issue," he said.
Obama's announcement of scaling back drone strikes was widely welcomed by the people of North Waziristan, where drones armed with missiles have carried out the most strikes against militants over the past seven years, sometimes with heavy civilian casualties.
The strike also coincided with the first session of the newly elected provincial assembly of Khyber Pakhtunkhwa, the former Northwest Frontier Province.
Former cricketer Imran Khan's Pakistan Tehrik-e-Insaf party won most seats in the assembly and denounced the strike, saying Obama had gone back on his word.
