Ukraine’s joint command has released a video showing shelling at the Shchastia crossing point north of the rebel-held city of Luhansk on Saturday. Several puffs of smoke can be seen as missiles land at and on the road. The footage was taken at 11.30am local time. The foreign ministry in Kyiv said Russia was targeting a humanitarian convoy from the office of the United Nations commissioner for refugees, as it returned from separatist-controlled territory. The attack represented a 'gross violation' of ceasefires agreements, it said.
