The Islamic State of Iraq and Syria (ISIS) terrorist group released the details of the assailants who carried out the deadly attack in Kabul city on Friday.

The offshoot of the terror group, ISIS Khurasan, posted a statement in Amaq News, claiming the deadly attack which left scores of people dead or wounded.

The statement further added that the group’s fighters, Ahmad Al-Tajiki and Abdur Rahman Al-Muhajir carried out the attack, killing or wounding at least 150 people.

The security officials said late on Friday that the attack which targeted the death anniversary of a prominent political leader in Kabul city left 32 dead and 81 others wounded.

The gunmen stormed the death anniversary ceremony of Anbdul Ali Mazari, a prominent Hazar leader on Friday as some of the key political leaders including Abdullah Abdullah and Mohammad Karim Khalili were present in the scene and were delivering speeches.

The Taliban group rejected the involvement of the group’s fighters in the attack.

Yesterday’s attack followed a steep rise in attacks across the country following the signing of a peace deal between U.S. and Taliban following a 7-day reduction in violence.

The latest surge in violence including Taliban attacks has sparked concerns that the growing violence may further delay the launch of intra-Afghan talks and the peace process.
