If verified,It would be the first major attack claimed by the ISIS group in the country.

"Who claimed responsibility for horrific attack in Nangarhar today? The Taleban did not claim responsibility for the attack, Daesh (ISIS) claimed responsibility for the attack," President Ghani said on a visit to Badakhshan.

A person purporting to be an ISIS spokesman claimed responsibility for the attack in a call to AFP and in an online posting.
