Four DAESH terrorists were decapitated by Afghan militias and their heads placed on the main road in Achin district of the eastern province of Nangarhar said local officials on Sunday.
The tension has increased between DAESH and local militias loyal to the Taliban.
DAESH is trying to increase its influence in districts controlled by Taliban militants.
Several members of a local militia force, who are loyal to Haji Zahir, deputy speaker of parliament, have recently started fighting both the Taliban and DAESH in the district.
Zahir told reporters that the militias decapitated the DAESH members as revenge, because DAESH caught four fighters from militia forces, known as Pasoon or "Uprising" and decapitated them.
Ataullah Khoqani, spokesman for the provincial governor said Afghan security forces were not involved in the incident but they are investigating it.
Meanwhile, DAESH members have been broadcasting radio show called "Voice of the Caliphate" in Nangarhar to attract young Afghans.
Last week, local officials stated that they had ended the broadcast, but Zahir said the 90-minute daily Pashto language broadcast is still broadcasting.
DAESH is currently a new force in Afghanistan and according to the US General John Campbell, the commander of international forces in the country, there are between 1,000 to 3,000 members of DAESH in the country.
