Officials in Pakistan had earlier reported about Sajna's death in a US strike.
Sajna was a leading figure of the Taliban and that both Pakistani and American security forces were after him for a long time.
According to Pakistani officials, Sajna was battle- hardened with experience of fighting in Afghanistan.
Sajna, in his early 40s, was believed to be involved in an attack on a naval base in Karachi and was credited with masterminding a 2012 jailbreak in which the Taliban freed nearly 400 inmates in the northwestern city of Bannu.
