Russia-Ukraine war: Key developments in the ongoing conflict

Russian airstrikes have hit three hospitals in Ukraine, including two west of the capital and a maternity hospital in Mariupol, where 17 people were wounded. Ukrainian officials labeled it a “war crime.” The attacks came amid hopes for mass evacuations of civilians from several besieged Ukrainian cities, including Mariupol, which has been without food, water and power for days and which started burying bodies in a mass grave because its morgues are full. Ukrainian President Volodymyr Zelenskyy said late Wednesday that about 35,000 civilians have so far used humanitarian corridors to flee the fighting.
