Local officials in Nangarhar province said on Monday the bodies of at least 10 local residents were found in a mass grave in Achin district.
The residents said all the deceased were killed by Daesh.
According to local officials the bodies were found in Momand Dara area of Achin district – which is known to be a Daesh stronghold.
Nangarhar provincial governor’s media office said the victims had been abducted from Pachiragam district by Daesh militants more than a year ago. They were later moved to Achin district.
This comes after another nine bodies were found in Kot district on Monday.
Tribal elders in Nangarhar province said these victims had also been killed by Daesh.
The funeral ceremonies for the deceased were held on Monday.
This is not the first time Daesh militants have abducted residents. Last year, in two separate incidents, Daesh abducted 14 teachers and ministry of education staff from the same district.
Some tribal elders in Nangarhar have also accused government of failing to do anything about rescuing these hostages.
But local officials rejected the claims and said security forces had tried to free them on a number of occasions.
