The HALO Trust, a UK-based demining NGO, is the only international organisation conducting demining in Nagorno Karabakh. They have destroyed 180,858 small arms ammunition, 48,572 units of "other explosive items", 12,423 cluster bombs, 8,733 anti-personnel landmines, and 2,584 anti-tank landmines between 2000 and 2016. By 2018, they had cleared 88% of the territory's minefields, with a target to clear the rest by 2020. The main cities of Stepanakert and Shusha, as well as the main north–south highway, have been cleared and are safe for travel. The demining effort has been largely funded by the United States Agency for International Development (USAID).
