The battle for Mariupol may be drawing to a close. Moscow claims over 1700 Ukranian soldiers have sureendered from the Azovstal steelplant, with almost 1000 taken to a prison colony in Russian-controlled territory.

In Ukraine's capital, the first war crimes trial of a Russian soldier is continuing. Simon McGregor-Wood has the latest.
