ISLAMABAD, Pakistan, Aug. 6 (UPI) -- U.S. officials believe there is a "strong indication" Pakistani Taliban leader Baitullah Mehsud was killed by a CIA drone strike, ABC News reported.
"Efforts are under way to determine for certain whether it was Mehsud, but there are hopes that it is him," an unnamed Obama administration official told the network.
"There is a strong indication" Mehsud was killed, the official said.
A Pakistani official told ABC officials are awaiting DNA tests to confirm reports of Mehsud's death.
The drone missile attack Wednesday on the home of one of Mehsud's fathers-in-law is believed to have killed three others as well, including Mehsud's second wife, ABC said.
Witnesses said Taliban and local residents pulled the woman's body from the debris, the BBC reported Wednesday.
The campaign against Mehsud, seen as an al-Qaida ally, has targeted the tribal Waziristan area close to the border with Afghanistan. Mehsud is accused of being responsible for suicide bombings and other attacks in the country.
