As reported by Censor.NET citing Politico magazine, this was announced by Ukrainian President Petro Poroshenko in his interview to CNN channel, calling Russia's activities in the Middle East "absolutely irresponsible."
He said he believed Russia's behavior in Syria was "absolutely irresponsible".
"At first it was the Crimea, second it was Donbas, third it is Syria, fourth, maybe, I don't know, Afghanistan," Poroshenko said.
According to the Ukrainian president, no one knows where to expect Russian 'green men' next.
Poroshenko said in New York during the UN 70th General Assembly in late September that fake information about Russia shifting from Ukraine to Syria was being spread by Russia-registered websites.
In his Oct. 9 interview with BBC the president said when commenting Putin's Middle East policy that Russian president wants global instability, comparing the operation of the Russian fighter jets in Syria to the situation in the Donbas, where according to Poroshenko, "15 months ago there were Russian soldiers."
