A senior Russian official said on Tuesday an announcement by Ukraine's president that he would hold a referendum on NATO membership in several years' time would increase regional tensions.
"I am convinced that what has been announced now by the Ukrainian leadership will only bring a further escalation of the situation around Ukraine," Interfax news agency quoted Deputy Foreign Minister Sergei Ryabkov as saying.
New arrivals of Russian supplies for rebels
The latest accusations come amid a standstill in diplomatic efforts to end the six-month conflict in the east in which the United Nations says more than 4,300 people have been killed.
Separately, the Kiev military said one soldier was killed and five others injured in the past 24 hours as a fragile ceasefire declared on Sept. 5 continued to come under pressure.
"The Russian side is continuing to provide the terrorist organisations of the Donetsk and Luhansk people's republics with heavy armaments," said a foreign ministry spokesman.
"Up to six of these were heavy armoured transporters. The rest were vehicles and buses carrying fighters and ammunition," he said.
Despite what Kiev's pro-Western leaders and Western government say is incontrovertible proof, Russia denies sending in troops to support separatist rebels trying to hive off parts of Ukraine's industrialised east and eventually join Russia.
Asked about reports of Russian humanitarian aid convoys entering Ukraine without authorisation, he said: "A significant amount of the goods which are being supplied ... is fuel, ammunition and other military help."
Perebyinis repeated an earlier charge that on Nov. 20, for the first time since a peace deal had been signed by Russia, Ukraine and the separatists, Ukraine had been subjected to artillery fire from the Russian Federation near the village of Kamyshine near the rebel-controlled border town of Luhansk.
