The Black Lives Matter group mourned and defended former Cuban leader Fidel Castro, and said it felt an “overwhelming sense of loss” after the death of the communist dictator on Friday.

“Although no leader is without their flaws, we must push back against the rhetoric of the right and come to the defense of El Comandante,” the group wrote in an unsigned editorial published Sunday titled, “Lessons from Fidel: Black Lives Matter and the Transition of El Comandante.”
