You don't survive that': Ukraine sappers dice with death to clear Russian mines

Ukraine is now the most heavily mined country on Earth and its army is suffering from a critical shortage of men and equipment able to clear the frontlines, the country's defence minister has said, as soldiers spoke of heavy casualties in the engineering brigades.

In an urgent appeal to allies, Oleksii Reznikov told the Guardian his soldiers were unearthing five mines for every square metre in places, laid by Russian troops to try to thwart Ukraine's counteroffensive.
