At least 40 people have been killed and 60 injured as religious clerics met at the Uranus Hall to celebrate the birthday of the Prophet Muhammad (pbuh), the Afghan interior ministry said.
At around 6:15 p.m. local time, the deadliest blast in Kabul in recent months targeted at least 1,000 people inside the hall. According to witnesses, the suicide bomber blew himself up in the middle of the gathering.
The blast has not been claimed by any terrorist organization, but the Islamic State group was behind most of the recent deadly attacks. The Islamic State group said it was behind two attacks in Kabul in August that killed dozens of people.
Dozens were also killed across the country as voters cast ballots in the nation's parliamentary elections in October .
