Beside an abandoned Russian military camp in eastern Ukraine, the body of a man lay decomposing in the grass — a civilian who had fallen victim to a tripwire land mine set by retreating Russian forces.

Nearby, a Cof Ukrainian minesweepers with the country’s territorial defense forces worked to clear the area of dozens of other deadly mines and unexploded ordnance — a push to restore a semblance of safety to the cities, towns and countryside in a region that spent months under Russian occupation.

The deminers, part of the 113th Kharkiv Defense Brigade of Ukraine’s territorial defense forces, walked deep into fallow agricultural lands on Thursday along a muddy road between fields of dead sunflowers overgrown with high weeds.

Two soldiers, each with a metal detector in hand, slowly advanced up the road, scanning the ground and waiting for the devices to give a signal. When one detector emitted a high tone, a soldier knelt to inspect the mud and grass, probing it with a metal rod to see what might be buried just below the surface.
