The actor Jeremy Renner from “The Hurt Locker” movie visited Afghanistan to shine a light on the efforts of the United Nations to remove landmines from the war-scarred country. Mr. Renner toured UN demining projects in Kabul, Bamyan and Bagram, took part in a mine risk education session with high school students, spoke with survivors of explosions and even ventured onto a minefield.

Afghanistan remains plagued by mines and explosive remnants of war, despite the ongoing efforts of the UN Mine Action Service (UNMAS) and the Mine Action Coordination Centre of Afghanistan (MACCA), as a result of decades of conflict. Mr. Renner said he saw first-hand the benefits of the UN’s activities, particularly in former minefields where farmers are now growing wheat, potatoes or other crops. “I’m a man of action and that’s why I like what the United Nations is doing here, action — mine action. We are not just talking about it, but taking action to solve this problem,” he said. “I’m here to be educated and then educate people about an issue that can be solved with the proper levels of funding.”
