A bomb has exploded in a wedding hall in the Afghan capital, Kabul, killing 63 people and wounding more than 180.
Witnesses told the BBC a suicide bomber detonated explosives during a wedding ceremony.
The explosion happened at around 22:40 local time (18.10 GMT) in an area in the west of the city mostly populated by Shia Muslims.
The Taliban denied they were behind the attack. No other group has admitted carrying out the bombing.
Sunni Muslim militants, including the Taliban and the Islamic State group, have repeatedly targeted Shia Hazara minorities in Afghanistan and Pakistan.
What do we know happened?
The Afghan interior ministry confirmed the death toll hours after the bombing. Pictures on social media showed bodies strewn across the wedding hall amid overturned chairs and tables.
Afghan weddings often include hundreds of guests who gather in large halls where the men are usually segregated from the women and children.
Wedding guest Mohammad Farhag said he had been in the women’s section when he heard a huge explosion in the men’s area.
“Everyone ran outside shouting and crying,” he told AFP news agency.
“For about 20 minutes the hall was full of smoke. Almost everyone in the men’s section is either dead or wounded. Now, two hours after the blast, they are still taking bodies out of the hall.”
The groom who gave his name as Mirwais told local TV: “My family, my bride are in shock, they cannot even speak. My bride keeps fainting.
“I lost my brother, I lost my friends, I lost my relatives. I will never see happiness in my life again.”
