The incident had occurred on Saturday night at the Dubai City wedding hall located in a western Kabul neighbourhood that is home to many in the country's minority Shia Hazara community.
The Islamic State has claimed the responsibility for the attack, believed to be the deadliest in the war-torn country this year.
Sources and eyewitnesses said that the hall was packed with guests when the explosion occurred. According to an Afghan-based journalist Bilal Sarwary, it was a Hazara wedding, which was targeted by a suicide bomber.
The Afghan government further announced the postponement of long-planned Independence Day celebrations in wake of the suicide bombing. It also postponed the inauguration of Darulaman Palace scheduled for Monday, Tolo News Reported.
