The Afghan Intelligence – National Directorate of Security (NDS) said the suspects were arrested during a special military operation conducted by intelligence operatives.
A statement by NDS said the detained militants have been identified as Nisar Ahmad, Nabullah, Obaidullah and Syed Sohail who were recruited by ISIS commander Rafiullah.
The statement further added that Rafiullah is leading a group of 20 militants in Achin district of eastern Nangarhar province.
NDS also added that the group was looking to assassinate police commander Sher Agha by detonating an Improvised Explosive Device (IED) planted under a culvert in Zarashkh area of Paghman.
The detained militants have confessed that they were affiliated with the ISIS terrorist group, NDS said.
This is the first time the Afghan security forces have arrested militants affiliated with the ISIS terrorist group from capital Kabul.
The militants are arrested amid concerns that the terror group is expanding its activities in various parts of the country by establishing foothold in remote parts of the volatile provinces including the eastern Nangarhar.
