Islamic State has claimed responsibility for a bombing at a wedding hall in Kabul that killed at least 60 people and injured more than 200. Survivors said the bomber was standing by a stage where children and adults were dancing and clapping when he detonated his explosives vest.

The bomb went off inside the the Dubai City wedding hall, in a western neighbourhood of Afghanistan’s capital that is home to many in the minority Shia Hazara community.

A statement by the militant group posted on an Isis-linked website on Sunday said the attack was carried out by a Pakistani Isis fighter. Isis has claimed responsibility for many deadly attacks against the Hazara community since the militant group emerged in Afghanistan in 2014.

The groom recalled greeting smiling guests in the afternoon and seeing their bodies being carried out hours later. The attack “changed my happiness to sorrow”, the young man, who gave his name as Mirwais, told a local TV station, Tolo News. “My family, my bride are in shock, they cannot even speak. My bride keeps fainting,” he said. “I lost my brother, I lost my friends, I lost my relatives. I will never see happiness in my life again.”

Mohammad Farhag, who attended the wedding, said he had been in the women’s section when he heard a huge blast in the men’s area. “Everyone ran outside shouting and crying,” he said. “For about 20 minutes the hall was full of smoke. Almost everyone in the men’s section is either dead or wounded.”
