Six Afghan Red Cross workers have been killed by suspected Islamic State (IS) group gunmen in the northern Afghan province of Jowzjan, officials say.
The workers were shot dead in the Qush Tepa area, said the governor.
Two others are unaccounted for, feared abducted by the group, he said. The ICRC confirmed the deaths but said it did not know who had killed its staff.
IS has been active in Afghanistan since 2015, claiming recent attacks in the east and Kabul.
There was no immediate claim for the attack in Jowzjan.
Government officials said the Red Cross staff were transporting supplies to areas affected by recent deadly snowstorms, Reuters news agency reports.
Taliban militants have also targeted the Red Cross in the past – its office in Jalalabad was attacked in 2013.
IS announced it was expanding into Afghanistan in January 2015 and has secured footholds in parts of eastern Nangarhar province, on the border with Pakistan.
