Two suicide bombers detonated explosive belts at a gathering of demonstrators of the local Shia Hazara Minority in Deh Mazang square on Saturday

Afghanistan is observing a day of national mourning following the suicide bombing of a protest march in the capital, Kabul, that killed 80 people and wounded more than 200 people.

Officials said, two suicide bombers detonated explosive belts at a large gathering of demonstrators of the local Shia Hazara Minority in Deh Mazang square on Saturday.

According to CNN, the demonstrators were marching to demand changes to the route of a planned power line.

Meanwhile, the Islamic State has claimed responsibility for the attack.

In a televised address, President Ashraf Ghani vowed to take revenge against those responsible.

The UN mission in Afghanistan has described the attack as a war crime.

Tadamichi Yamamoto, head of the UN assistance mission, said the attackers had specifically targeted a large number of civilians.

On Saturday, Afghan President had said he was deeply saddened over the incident.

He said, 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.
