About 27% of Ukraine's territory will need to be cleared of mines and explosives, according to the latest estimates by the ecology ministry nearly six months since Russia began its invasion and bombardment of its neighbour.
So far Ukrainian authorities have cleared more than 620 square kilometres (240 square miles) of land that were littered with thousands of explosive devices, including 2,000 bombs dropped from the air.
Nearly 300,000 square kilometres (116,000 square miles) are still seen as "contaminated", according to data released by Ukraine's Emergency Services. Making that area safe could take a decade, the government said.
