DERA ISMAIL KHAN, Pakistan — Pakistani Taliban militants have chosen a new deputy commander to replace their previous second-in-command who was killed in a US drone strike in the North Waziristan region, sources in the militant group said on Thursday. The sources also said the Taliban are withdrawing their offer of peace talks. The previous deputy commander, Wali-ur-Rehman, was killed in an attack by a missile-firing US drone aircraft in the militant stronghold of North Waziristan, on northwest Pakistan's border with Afghanistan, on Wednesday, Pakistani security officials and militants said. A Pakistani Taliban committee met late on Wednesday to chose a new deputy after Wali-ur-Rehman was buried in a low-key ceremony, three Taliban members told Reuters. The Taliban members said the new number two, Khan Said, 38, had served as Rehman's deputy. He was involved in planning a 2011 attack on a Pakistani navy base in Karachi in which 18 people were killed and a 2012 jail break in which nearly 400 militant inmates escaped, they said. “There was absolute consensus over Khan Said,” one Pakistani Taliban member said. Wednesday's drone strike, that killed six other people, was the first in Pakistan since a May 11 general election in which strikes by the unmanned US aircraft was a major issue. The Pakistani Taliban are a separate entity to the Afghan Taliban, though allied with them. Known as the Tehreek-e-Taliban Pakistan, they have launched devastating attacks against the Pakistani military and civilians. Wali-ur-Rehman had been tipped to succeed Hakimullah Mehsud as leader of the Pakistan Taliban and had been viewed as someone less hostile to the Pakistani military than some other top operatives. Peace effort? While his death is a major blow for the militants, it could be also viewed as a setback for incoming Prime Minister Nawaz Sharif's efforts to end violence. He criticized drone strikes during the election campaign, describing them at one point as a “challenge” to Pakistan's sovereignty. “Wali-ur-Rehman was a serious and mature man, his death could hurt prospects for an expected peace initiative considered by the new government,” the official told Reuters. However, many observers said any meaningful settlement with the Taliban was unlikely in any case given Sharif's condition that the starting point for talks be respect for the country's democratic order and institutions. The White House did not confirm the killing, in line with its practice not to discuss drone strikes. But its spokesman Jay Carney said Wali-ur-Rehman “has participated in cross-border attacks in Afghanistan against US and NATO personnel and horrific attacks against Pakistani civilians and soldiers.” Drones armed with missiles have carried out numerous strikes against militants in the North Waziristan Pashtun tribal region over the past seven years, sometimes with heavy civilian casualties. — Reuters
