Interior Minister Arseny Avakov said tanks entered Ukraine through checkpoint controlled by pro-Russian separatists in the Luhansk region
Russia has denied aiding the separatists, who have taken control of several towns and cities in mainly Russian-speaking east Ukrain
‘Over the last three days, despite Russia’s statements welcoming the peace process, a column has been sneaking into the area of Dyakove through checkpoints seized by terrorists,’ he said.
‘We have registered the passage of a column including APCs, armoured vehicles with cannons.
‘Today we see three tanks which, according to our information, crossed the border and were in Snizhne.’
Mr Avakov claimed there was a ‘fight’ going on with the column – which was not believed to be displaying Russian colours.
‘Part of this column has been destroyed,’ he said.
