This is the moment Russian sappers demine the bombed-out Azovstal plant in Mariupol, Ukraine.

Russian troops stormed the plant on 19th April and destroyed large areas. However pockets of organised resistance fighters of the Azov Battalion, a far-right unit of the National Guard of Ukraine, holed up in the plant and mounted a brave resistance.
