Pakistani terrorist killed in Aleppo defaming Pakistan around the world

Notorious Deobandi militant belonging to proscribed ASWJ (Lashkar-e-Jhangvi) was killed in Syrian city Aleppo where he had gone to perpetrate terrorist attacks on Syrians. But, his presence and killing in Syria has again brought a bad name to Pakistan because it was proved that Pakistani Deobandis continued to perpetrate terrorism abroad.

Umer Punjabi originally belonged to Sipah-e-Sahaba (ASWJ) and its sister-wing Lashkar-e-Jhangvi that were banned by the Pakistani government. He also worked for Taliban. All these Deobandi terrorist outfits were involved in massacre of innocent Pakistanis in all over Pakistan.
Syrian army killed Umer Punjabi when he was engaged in a war on Syrians in Aleppo. Deobandis have released news of his killing on social media and termed his journey to hell as martyrdom because they always called Pakistan Army not martyrs but Taliban’s Hakimullah Mehsud as martyr. Deobandi Fazal ur Rehman had argued that if a dog is killed due to U.S. attack, that dog would be called martyr. Hence, no matter, dogs may also be called martyrs, according to Deobandis.
Umer Punjabi’s presence and killing in Syria has raised questions about the State policy of Pakistan as how Pakistanis were being sent to Syria to fight Saudi’s proxy war there. Why Pakistani authorities have failed to stop them?
