ISLAMABAD, Oct. 18 (Xinhua) -- The recent U.S. drone strikes along the Pakistan-Afghanistan border had killed the mastermind of the deadly attack on a Pakistani school that left 144 kids and teachers killed, local media reported Wednesday.
The militant, known as Umar Mansoor, claimed responsibility for the attack on the school located in capital city Peshawar of Pakistan's northwest Khyber Pakhtunkhwa province in 2014, and later another attack at Bacha Khan University in 2016, which left 22 people killed.
Mansoor was among over two dozen militants who were killed in a recent string of drone strikes, a few km away from Pak-Afghan border in Afghan's province of Pakita, ARY News said.
The report added that the commander got injured in Tuesday's drone strike and was shifted to some "safe place" by the militants where he succumbed to injuries.
In an email to local media, proscribed organization Tehreek-i-Taliban Pakistan (TTP) confirmed Mansoor's death, saying that he was the commander of Dara Adam Khel and Peshawar chapter.
TTP spokesperson Muhammad Khorasani said that they had chosen militant commander Khalifa Usman Mansoor Hafizullah to replace Omar Mansoor.
