Pakistan held funerals on Monday for victims of a massive suicide bombing that targeted a rally of a pro-Taliban cleric the previous day as the death toll climbed to at least 54 and the government vowed to hunt down those behind the attack.

No one immediately claimed responsibility for Sunday’s bombing, which also injured nearly 200 people. Police said their initial investigation suggests the Islamic State group’s regional affiliate could be behind the attack.
