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 it was 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.
The latest blast comes just 10 days after a huge bomb outside a Kabul police station killed at least 14 people and injured nearly 150.
The Taliban said it carried out that attack.
On Friday a brother of Taliban leader Hibatullah Akhundzada was killed by a bomb planted in a mosque near the Pakistani city of Quetta.
No group has so far claimed that attack.
A source in Afghan intelligence told the BBC that Hibatullah Akhundzada had been due to attend prayers at the mosque and was probably the intended target.
Tensions in the country have been high even though the Taliban and the US, which has thousands of troops stationed in Afghanistan, are reportedly getting closer to announcing a peace deal.
