My Grandma Katharina is turning 99 on February 23rd. She was born in Ukraine and came to the UK in 1947 to marry my Grandad after escaping Ukraine during the Second World War. The current crisis has brought back many memories of her childhood and she wants to do something to help.

She will be walking 99 laps of the building she lives in of at least 300m each before her birthday.

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.
