The group issued a statement online after the attack left several people dead or wounded at the end of the religious scholars gathering in Kabul.
The group called the religious scholars as ‘tyrant clerics’ and said the attack was carried out as they had gathered in a meeting in Kabul.
This comes as the Taliban group had earlier rejected their involvement in the attack.
The Kabul Police officials are saying that the attack took place at around 11:30 local time on Monday as the religious clerics were leaving the Loya Jirga camp where the gathering had taken place.
Kabul Police spokesman Hashmat Stanikzai said at least seven people were killed and at least nine others were wounded in the attack.
However, other sources are saying that the attack left at least 14 dead while nearly 20 others have sustained injuries.
