Russia’s war on Ukraine is now in its third week and Vladimir Putin has approved bringing in “volunteer” fighters from the Middle East and elsewhere to join the war. Russian forces appeared to be expanding their offensive on Friday and striking new areas in western Ukraine. Ukraine says 100,000 people were evacuated over the past two days in a total of seven cities in the north and center of the country. The humanitarian corridors were agreed to by Russia and Ukraine. More evacuations are expected, though repeated attempts to reach the besieged port city of Mariupol in the south have failed amid continued Russian shelling.
