Some relatives of people stranded in flooded villages following the collapse of the giant Nova Kakhovka Dam in southern Ukraine said on Friday that their loved ones were still stuck on roofs with dwindling food supplies and urgently needed rescuing. Volunteers and workers from Russia's Emergency Situations Ministry have been evacuating people from flooded Russian-controlled areas since Tuesday's disaster - which Moscow and Kyiv blame on each other. The Kremlin has praised the rescue efforts, as have some of the people who have been evacuated to safety.
