US peace envoy to Afghanistan Zalmay Khalilzad on Twitter condemned the attack on the human rights workers that occurred on Saturday, calling it anti-human.

The targeted killing of Fatima Khalil and Jawid Folad, two Afghans dedicated to the cause of fundamental human rights, is an anti-human act. We condemn this terrorist attack in the strongest possible terms, Khalilzad tweeted.

We support the overwhelming demand of Afghans to overcome these odds and continue the march to a permanent and dignified peace and an Afghanistan in which everyone’s rights are respected.

Two employees of the Afghanistan Independent Human Rights Commission (AIHRC) were killed in an IED explosion that targeted their vehicle in Kabul on Saturday, the commission confirmed.
