Aziz was responsible for the department in LeT that provided support to families of terrorists killed in encounters in Jammu and Kashmir.
His sudden death comes just days after a senior LeT operative, Rizwan Hanif, made shocking admissions about the deaths of over 30 members by "unknown men" within Pakistan.
In a video statement, Hanif revealed that many members have been killed across different regions, including Peshawar, Karachi, Rawalpindi, Rawalakot and Muzaffarabad over the past three to four years.
