Afghanistan wedding bomb blast death toll rises to 80  

The death toll from a suicide bomb attack at a wedding hall in Afghanistan's capital Kabul has risen to 80.

The initial death toll stood at 63 on Sunday, a day after the blast, which jumped to 80 by Wednesday.

Interior Ministry spokesman Nusrat Rahimi said 17 civilians succumbed to their injuries in recent days.

He added that 30 people were in critical condition after the attack.

"Seventeen others have succumbed to their injuries in hospital and over 160 are still being treated either in hospitals or at home," Rahimi said.

The blast was so powerful that it blew much of the roof off the huge wedding hall, where hundreds of guests had gathered.

The Islamic State (IS) militant group claimed responsibility for the attack.

It was Kabul's deadliest attack since January 2018 when the Taliban packed an ambulance with explosives and detonated it in a crowded street - killing 103 people, according to an official toll.

Many Afghanistan independence day celebrations that were scheduled to take place on August 19 were suspended in the aftermath of the horrific attack.

So far, security officials have yet to provide any explanation as to why the wedding was targeted.

Afghanistan President Ashraf Ghani strongly condemned the attack, vowing to "take revenge for every civilian drop of blood".

"Our struggle will continue against [ISIL], we will take revenge and will root them out," he said on Monday.

He urged the international community to join those efforts.
