The military funds for Pakistan, however, include a condition which requires Islamabad to a decisive action against the Haqqani network and other terrorist groups to receive the assistance.
The Tehreek-e-Taliban Pakistanconfirmed on Monday that their deputy leader was killed in a suspected United States drone strike last week and said they had appointed a new deputy in his place.
However, the Pakistani media had reported earlier that Sajna came under the attack in Afghanistan's eastern Paktika province, bordering Pakistan.
The spokesman said Taliban chief Mullah Fazlullah immediately replaced Mehsud with another commander, Mufti Noor Wali.
Four insurgents including a foreign national have been killed as government forces stormed a base of Taliban group in Jurm district of the northern Badakhshan province on Tuesday, an army spokesman in the region said.
In May 2016, the leader of the Afghan Taliban, Mullah Mansour, was also killed in a U.S. drone strike in Pakistan, meeting the same fate as the head of TTP, Hakimullah Mehsud, did in 2013.
Militant sources said Wali, known by the nickname Ghar Starga, is a ruthless leader with experience working in Pakistani urban areas including the southern city of Karachi.
Many TTP militants have sought refuge in Afghanistan. Much of the border with Pakistan s northwestern tribal areas is off-limits to foreign journalists, and strikes along the porous frontier are hard to verify.
Mehsud has kept militant attacks going not only against military targets in South Waziristan but also at times deeper inside Pakistani territory.
