There are striking similarities between the Imamia Imambargah attack and Army Public School [APS] attacks in Peshawar.
The terrorists who attacked the imambargah on Friday set their vehicle ablaze similar to the APS assault. On December 16, 2014, attackers had reached the school in a van and destroyed it by setting it alight before entering the school premises.
In the APS assault, the terrorists used Russian-made hand grenades and the same type of grenades were recovered from the Imamia Imambargah in Hayatabad.
In both the attacks, the terrorists used a dual-trigger mechanism for their bombs.
