“I would be very careful about speculating on any links between Ukraine and the Russian presence in Syria. What we know is that Russia still has substantial forces, both along the border to Ukraine and also inside Ukraine,” said Stoltenberg, according to Ukraine Today.

“Russia still has forces, equipment, command and control and they help and they train the separatists. So there is still a substantial Russian military presence, both close to the borders of Ukraine and also inside Ukraine,” he said, calling the current situation in Donbas “very fragile” despite lull in the fight.
