The Islamic State (IS) has claimed responsibility for the explosion at a mosque in the Pakistani city of Peshawar that claimed over 50 lives, media reports said on Saturday.
On Friday, two terrorists opened fire at police officers near the mosque in Peshawar, after which one of them entered the building and staged the explosion. The attack left 57 people killed and more than 200 injured.
UN Secretary-General Antonio Guterres on Friday condemned the suicide blast, saying "houses of worship should be havens, not targets.
