Security sources in Pakistan said that Padshah Khan Mehsud, one of the senior commanders of the Tehreek-e-Taliban Pakistan (TTP), had been injured in an attack in Afghanistan on Sunday.
Mehsud is believed to be the TTP leader Noor Wali Mehsud's "right-hand man" and confidant.
However, Afghanistan International's sources did not mention who targeted Mehsud.
So far, there is no information about his health condition.
TTP has not officially confirmed or denied attack on Mehsud or his injury.
