A top ISIS leader who helped found the terror group has been killed during a firefight in Afghanistan, security forces say. Emarati was killed in a firefight along with 120 other suspected militants, according to the Afghan army.
Saad Emarati was one of the founders of the IS group's Afghanistan-Pakistan branch, and led several attacks against the Taliban and the government.
Afghan officials say he was one of about 120 suspected militants killed in an operation in Kot district.
It comes days after a bomb attack in Kabul claimed by IS killed 80 people.
Emarati was formerly a Taliban commander, but switched allegiance to IS following the death of Mullah Omar, the Taliban founder.
Analysts say he was one of the most important leaders of IS in the region, and that his death, if confirmed, would be a serious setback to the group's ability to operate in eastern Afghanistan.
Afghan officials have released photos following the overnight raid in Kot, showing IS courts and recruitment centres seized by the military.
Afghan special forces commander Gen Basmullah Wazari said the operation had received foreign air support.
Emarati was one of the first militant commanders in the Afghanistan-Pakistan region who pledged allegiance to IS's leader Abu Bakr al-Baghdadi.
