Abdullah Wazirstani, spokesman for North Waziristan Taliban, a group linked to the Pakistani Taliban, said the strike killed three civilian “labourers” and seven militants from the Pakistani Taliban, which is also known as TTP.
Malik Waheedullah, a local tribal leader, told Reuters he saw two missiles strike a mountain home which caught fire. “I drove away as fast as I could,” he said.
One Pakistani intelligence official and government source said they believed the strike to be a US drone attack.
US officials did not immediately respond to requests for comment.
North Waziristan was a Taliban stronghold until 2014, when Pakistan’s military launched a major offensive against the group and pushed many of its fighters across the border into Afghanistan.
Sources from the TTP identified one of the dead militants as Abdur Rahman, a senior commander of the Pakistani Taliban.
U.S. drone attacks inside Pakistan have become rare over the past few years. In its last high-profile attack inside Pakistan, the United States last May killed Afghan Taliban leader Mullah Akhtar Mansour in the southwestern province of Baluchistan.
