Armed men had kidnapped the four men, two women and one child found beheaded last month.
Afghan President Ashraf Ghani on Monday condemned the beheading of a group of Shia Hazaras, including a child, in the southern province of Zabul, the scene of deadly clashes between rival Taliban groups.
Local officials in Zabul province said the headless bodies of four men, two women and one child, who were kidnapped by armed men in October from neighboring Ghazni province, were found in Khak-i-Afghan district on Sunday.
The circumstances surrounding the beheadings are unclear. Some local officials pointed the finger at fighters from the Islamic State group in the province, but the government does not have control of the area and the claim could not be independently verified.
Groups associated with I.S. have made growing inroads in Afghanistan this year, attracting fighters and support away from disenchanted members of the Taliban.
“The heartless killing of innocent individuals, especially women and children, has no justification in any religion or creed,” Ghani said in a statement. Ghani, who was “profoundly saddened” by the killing, said he would convene “an extraordinary security meeting to seek ways for tracking down and punishing the perpetrators of this atrocious crime” later on Monday.
The U.S. also issued a statement condemning “yesterday’s beheading of seven civilians, including women and a child” through its embassy in Kabul.
