At least 80 people were killed, and more than 230 wounded, in Kabul on Saturday by suicide bombers who targeted a peaceful protest march by ethnic Hazaras, a minority Shia group in Afghanistan.

“We were holding a peaceful demonstration when I heard a bang and then everyone was escaping and yelling,” Sabira Jan, a protestor who witnessed the attack and saw bloodied bodies strewn across the ground, told Reuters. “There was no one to help.”

In a statement issued by its news agency, Amaq, the Islamic State (ISIS) militant group claimed responsibility for the attack – reported as the deadliest in Kabul since the U.S. invasion overthew the Taliban government in 2001.
