In April the U.S. Forces - Afghanistan (USFA) dropped the so-called Mother of All Bombs (MOAB) on Daesh hideouts in the neighboring Achin district of Nangarhar province.
A top Afghan Army official has said that at least 700 Islamic State (ISIS) militants were killed in Afghanistan's Nangarhar province in the past three months during the Hamza operations.
Khan has been described as a senior communicator, experienced media production director and a skilled propagandist for ISIS in Afghanistan, known as Islamic State-Khorasan Province. ISIS-K claimed responsibility.
"His death will disrupt the ISIS-K network, degrade their recruitment process and hinder their attempts to conduct worldwide operations", Gen. John Nicholson, commander of USFOR-A said in the statement.
Such a figure is not unusual for the Afghan military, which loves to claim gaudy death tolls in their highest profile operations, but does conflict with the public narrative that the ISIS affiliate in Afghanistan is very small and very aspirational.More news: Television Batman star Adam West dies at 88
