The United Nations says more than half of Ukraine’s children have been forced to flee their homes in the month since Russia invaded Ukraine. It’s one of the largest mass displacements of children since the Second World War. This morning, Ukraine’s military said it destroyed a large Russian landing ship docked in the occupied city of Berdyansk on the Black Sea. In northern Ukraine, about 150,000 residents of Chernihiv are without heat and electricity and have been forced to ration drinking water, after Russia bombed a key bridge linking their city to the capital, Kyiv. Ukrainian officials have accused Russian forces of holding Chenihiv hostage amid fears it could suffer the same fate as Mariupol, the besieged Black Sea port city that’s been devastated by weeks of Russian attacks.
