A suicide bomber blew himself up in the Afghan capital Kabul today, killing more than 50 people, three government officials said.
Najib Danish, a spokesman for the interior ministry, said more than 70 other people were injured in the attack.
"A suicide bomber detonated his explosives inside a wedding hall where Islamic religious scholars had gathered to commemorate the birthday of Prophet Mohammad," Danish said.
There were no immediate claims of responsibility for the blast.
There was no immediate claim of responsibility for the blast, but the Islamic State group has claimed most recent suicide attacks in Kabul, which has become the deadliest place in the country for civilians.
It is the bloodiest assault in the Afghan capital since a twin bomb attack on a wrestling club in September that killed at least 26 people.
Last month's parliamentary elections sparked a wave of deadly violence across the country, with hundreds killed or wounded in poll-related attacks.
It is not the first time that religious scholars have been targeted by militants in the deeply religious country.
In June a suicide bomber struck near a gathering of clerics in Kabul, about an hour after the group had proclaimed such attacks a sin.
The latest attack comes as the Taliban intensifies pressure on Afghan security forces, even as the international community ramps up efforts to convince the group to engage in peace talks.
