we begin in ukraine where the government in kyiv has reacted with anger after a russian general seemed to suggest a new battle plan which would effectively cut ukraine off from its black sea coastline. it would see russian forces advancing towards a pro moscow enclave in moldova. ukraine says that is just imperialistic. moldova has summoned the russian ambassador there to explain. meanwhile the un says there s growing evidence of war crimes being committed in ukraine, describing the situation as a horror story. us satellite images allegedly show a mass burial site, containing around 200 graves, near the beseiged southern port city of mariupol, that russian forces have been trying to fully capture for several weeks. they do control most of the area, but hundreds of ukrainian troops, are still hiding out in the sprawling azov stal steel plant.
