The photographs were published by the loyalists of the terror group in social media earlier this evening.
The authenticity of the photographs could not be independently verified and it is yet not in which part of the country the militants were executed.
Subtitles in Arabic language in the photographs identify the men as Abdul Ghafoor, Mohammad Rahim and Fazal-ur-Rehman.
The photographs shows three men blindfolded and are shot dead by the ISIS loyalists as they have been given orange jump suits.
This is the first time the terror group’s loyalists have published the execution photographs of the Taliban group in Afghanistan.
The Taliban militants group has not commented regarding the report so far.
The photographs are released as the loyalists of the terror group were hardly suppressed in Afghan and US forces raids.
The raids against the loyalists of the terror group intensified in parts of Nangarhar province amid concerns that they are attempting to expand foothold in the country.
A spokesman for the US-led coalition forces in Afghanistan earlier said the Islamic State of Iraq and Syria (ISIS) terrorist group has the potential to be an ‘enormous’ threat in Afghanistan.
The chief of communications for the coalition, Brigadier General Charles Cleveland, said last month the threat exists despite the group has received major setbacks during the recent months, pointing towards the growing US forces airstrikes against the loyalists of the terror group.
