In Ukraine an area of land that represents 174,000 square kilometres – around the size of England, Wales and Northern Ireland combined – has been contaminated by landmines.
Both Russia and Ukraine have been using these explosive devices – which can be triggered by tripwires or booby traps – during the war.
The devices are mostly concentrated in the Kharkiv region of the country and officials have said it will take decades to clear them all.
