ISIS attack in Afghanistan kills 80 and wounds 230 during strike on protest march
Ferocious attack even condemned by hardline Taliban, while a would-be third bomber is killed by security forces
ISIS have claimed responsibility for a double suicide bombing in Afghanistan's capital Kabul which has killed 80 and wounded 230 people.
The attack happened shortly after midday during a protest march, with bombers targeting the Shia Hazara minority sect.
The ISIS-backed Amaq news agency claimed: "Two fighters from Islamic State detonated explosive belts at a gathering of Shi'ites in the city of Kabul in Afghanistan."
Charred bodies of the victims could be seen on the streets in the aftermath of the attack, believed to be the largest ever ISIS has ever committed in Afghanistan.
The death toll is expected to rise.
Afghan president Ashraf Ghani spoke on national television to declare a day of national mourning.
He vowed: "I promise you I will take revenge against the culprits."
"Peaceful protest is the right of every citizen, but opportunist terrorists infiltrated the crowds and carried out the attack."
The march had been protesting against plans for a new power line which is planned to be built through the area in which many of the victims lived.
The protests and the attack, a sign of increase in sectarian violence in the country, place pressure on Ghani's administration which has faced criticism in recent months.
