Summary and Key Points: Ukraine is now one of the most heavily mined countries on earth. Current U.S. and international estimates put contaminated territory at approximately 139,000 square kilometers — more than a fifth of Ukraine, larger than Greece, and roughly the size of North Carolina.
-The mines include antipersonnel mines, anti-tank mines, cluster munitions, unexploded artillery shells, drone-dropped munitions, and booby traps.
-One estimate has put the cost to Ukraine at more than $11 billion in lost annual GDP.
