As you know, the humanitarian situation is increasingly dire and desperate. Millions of people have no safe place to call home. More than 2.5 million have already left Ukraine, while countless more are still trapped underground, taking cover from the shelling, and desperate for a safe escape.Red Cross teams have been working around the clock to get critical care to those who need it most, both in Ukraine and its bordering countries. But with recent freezing temperatures, and ongoing violence, an enormous number of people urgently need help right now.
