A rebel leader in eastern Ukraine has said a convoy of military hardware is on its way to the region from Russia.
Alexander Zakharchenko, self-proclaimed PM of the Donetsk rebel area, said on Friday 150 vehicles and 1,200 personnel were approaching their border.
Russia has denied claims by Ukraine and Western reporters that military aid to the rebels is crossing over.
Meanwhile a controversial humanitarian aid convoy from Russia is stalled on the Russian side of the border.
'Good news'
Mr Zakharchenko, who became self-declared prime minister of the "Donetsk People's Republic" (DPR) last week, is seen on a video posted on YouTube addressing the region's self-styled parliament.
"I'd like to give you some good news," he says. "At present, moving towards the corridor [a link across the border into Russia established by the rebels] are... 150 items of military hardware, 30 of which are tanks and the rest are infantry fighting vehicles and armoured personnel carriers.
