Trench warfare: Fighting in the winter months

As troops grapple with freezing temperatures and missiles cause mass power cuts across Ukraine, the BBC’s Security Correspondent Frank Gardner assesses both sides’ military strategies.

And Father Vitaliy Novak describes how he and a team of volunteers are delivering food to people across the country, some of whom are living in church basements.
