Afghanistan is marking a national day of mourning a day after at least 80 people were killed by a suicide bomber attack on a peaceful demonstration. The attack was claimed by the Islamic State group.

Funerals were due to begin quietly in western Kabul on Sunday. Authorities say another 231 people were wounded, some seriously, in the attack Saturday afternoon on a march by members of the ethnic Hazara community, who are predominantly Shiite Muslim. Most Afghans are Sunni, and the IS group regards Shiites as apostates.

The Ministry of Interior has banned all public gatherings and demonstrations for 10 days. The square where the attack took place remains closed by Hazara protesters.

The IS group has had growing a presence in Afghanistan for the past year.
