ISLAMABAD - Authorities in Afghanistan say the death toll has risen to more than 63 and injured to 183 in the overnight suicide bombing at a packed wedding hall in the capital, Kabul.
The victims were mostly members of the minority Shi'ite Hazara community.
Afghan Interior Ministry spokesman Nasrat Rahimi confirmed the casualty toll in a statement issued early Sunday, saying women and children were among the victims.
There were no immediate claims of responsibility for the carnage, one of the worst attacks against Afghan civilians in recent years.
The Taliban denied its involvement and condemned the bombing. A spokesman for the insurgent group said "such barbaric deliberate attacks against civilians including women and children are forbidden and unjustifiable."
Almost all recent bombings in the city, particularly against the Hazara community, have been claimed by Islamic State's Afghan branch, known as Khorasan Province.
Rahimi in a statement he issued shortly after the attack said the blast occurred just before midnight on Saturday and police and ambulances quickly reached the site to transport victims to Kabul hospitals.
Civilians continue to bear the brunt of the conflict in Afghanistan, where more than 1,500 were killed or wounded in July alone, according to the United Nations.
The latest Afghan violence comes as peace talks between the United States and the Taliban have come close to reaching an agreement to end the 18-year-old war.
