Eighty dead in IS bomb attack on Afghanistan's Shia
The Islamic State group claimed the attack via the Amaq news agency which is linked to the jihadis, saying that two fighters "detonated explosive belts at a gathering of Shia".
Thousands of members of Afghanistan's Shia Hazara community had gathered to protest about a new power line, which they say bypasses their provinces.
According to the BBC, a local journalist reported seeing bood and body parts everywhere around the scene of the blast.
The Taliban's spokesperson Zabiullah Mujaheed contacted journalists via email to condemn the attack.
The Hazara make up Afghanistan's third largest group, however have often come into sectarian conflict with the Taliban and other religious extremists in Afghanistan.
IS militants regard Shias as disbelievers, and have targeted their communities around the world.
Afghan President Ashraf Ghani said he was "deeply saddened" by the atrocity, adding that "peaceful protest is the right of every citizen, but opportunist terrorists infiltrated the crowds and carried out the attack, killing and injuring a number of citizens including some security forces."
