The Russian occupiers have mined many civilian apartments in Bucha, where they found Ukrainian symbols or soldier’s documents, said Minister Denis Monastyrsky. “According to international standards, one day of active hostilities means a month of demining,” said the minister. On just April 4 alone, rescuers found more than 4,000 explosive devices. According to mine specialists, these are defined as unexploded ordnance, explosive remnants, and mine-extensions in houses. Bucha residents cannot return home yet, and it will take some time to clear the area.
