Siraj Raisani was about to address an election rally when a suicide bomber, carrying around 16–20 kg of explosive material in his vest, blew himself up among a crowd of more than 1000 people. Along with Raisani, the explosion killed 128 people. Two days after the attack, on 15 July 2018, the number of dead increased to 149, while 186 other people were injured, making it the deadliest terrorist attack in Pakistan since the APS massacre in Peshawar in 2014.
