Ten members of The HALO Trust (Hazardous Area Life-support Organization), which works to remove debris left behind by war, were killed in Afghanistan and another 16 were injured in the attack on Tuesday. Prince Harry has worked with the organization on multiple occasions and visited a HALO Trust mine site in Angola in 2019 — 22 years after his late mother Princess Diana's poignant walk through a minefield in the same country. "In all, 26 members of The HALO Trust's Afghanistan team were killed or injured on Tuesday night in what was nothing less than an act of barbarism," he said in a statement released Thursday. "I honour those who have been lost and encourage support for the survivors and the families of those affected." "Those who work for HALO in Afghanistan face risks every day to remove the lasting — and still deadly — scars of war and conflict," continued Harry, 36. "The men who were attacked come from the very communities in which they work. They joined HALO to protect and restore their country and their homes. As I understand it, the deminers who lost their lives were also protecting their friends." Prince Harry Follows in Mom Princess Diana's Footsteps by Visiting Angola Landmine Field Prince Harry added, "These workers put their lives on the line every day to make the world a safer place. This brutal act reminds us that we must stand in solidarity with humanitarian aid workers and the communities they serve. I would urge all of HALO's supporters across the world to rally to their cause and help in any way they can." Can't get enough of PEOPLE's Royals coverage?
