This time, the responsibility for the blast has been claimed by three militant factions, two of them being breakaway groups of Tehreek-e-Taliban Pakistan (TTP), reported media.
The terror factions claiming their roles in the attack are Jundullah, Jamat-ul-Ahrar and a non-descripit Mahar Mehsud group.
Anti-Shia group Jundullah, the first group to have claimed the attack, is also said to have carried attacks like 2004 attack on Karachi Corps Commander, September 2013 Peshawar church bombing, June 2013 murder of tourists in Gilgit-Baltistan, and February 2012 Kohistan Massacre.
Ahmaed Marwat, the group's spokesperson, claimed the attack at Wagah border, saying it was in retribution to Pakistani Army's Operation Zarb-e-Azb.
Former Tehreek-e-Taliban spokesman Ehsanullah Ehsan has also claimed that its Jamat-ul-Ahrar group was responsible for the deadly suicide attack at Wagah border. Ehsan also said that he would soon release the video of the attack that he said was carried out by a member of his group named Hafiz Hanifullah.
The suicide attack carried out at Wagah border crossing on Sunday, Nov 2, killed over 60 people and injured over a hundred.
The suicide bomber detonated his explosives-laden vest while scores were returning after watching the flag-lowering 'beating retreat' ceremony.
