According to a statement released by NDS on Sunday, Qari Muzamil alias Hakimullah was killed along with four of his men in Behsood District of eastern Nangarhar province.
The statement does not specify whether the militants were killed in security operations or drone strike.
This comes amid reports that militants are trying to mobilize in Deh Sabz District. The killing of Qari Muzamil could potentially affect Taliban lines in Deh Sabz.
Statements released by NDS usually do not contain exact date of the achievements but they come after recent activities.
