US defence secretary Lloyd Austin has committed to keeping US weapons moving to Ukraine as Kyiv faces one of its toughest moments against a renewed assault by Russia.

Mr Austin and as many as 50 defence leaders from Europe and around the world are meeting on Monday to coordinate more military aid to Ukraine, as Kyiv tries to hold off a Russian offensive in the north-east while launching its own massive assault on the Russia-occupied Crimean Peninsula.
