As Ukraine and Pro-Russian separatists agreed to a ceasefire in eastern Ukraine, the deputy NATO military commander said Moscow must be judged by its actions, not its words.
"If [the ceasefire] is the portent of a peaceful solution to this conflict in eastern Ukraine that's welcome news. But I think we need to judge things by actions and not by words,” General Adrian Bradshaw told CNN’s Christiane Amanpour on Friday.
“I'm afraid during this crisis in the past we've heard words said which haven't been reflected by actions on the ground. So we need to just ensure that people are being genuine here."
Fighting continued in eastern Ukraine on Friday, with shelling reported around the city of Mariupol. If separatists took that city, it could provide a land bridge between Russia and Russian-annexed Crimea.
Amanpour asked whether Russia is indeed trying to establish that land bridge.
"Their strike in that direction does beg that question. I wouldn't presume to guess what the Russian intent is at the end of this whole affair.”
“I think what is important for us to focus on is what they are doing is illegal, unacceptable, and is just not the way that one expects nations in Europe to conduct international affairs."
In an interview with Amanpour also on Friday, Russia's Permanent Representative to the OSCE Andrey Kelin denied that there were any Russian troops in Ukraine.
Nonetheless, Kelin said, “there is quite a number of the Russian volunteers, probably former military men that are fighting on behalf of the freedom fighters.”
Bradshaw refuted that account.
"We already know now that there are Russian regular forces on the ground in Ukraine, operating in main battle tanks, employing artillery fire, and delivering all sorts of support to separatists.”
“This sort of armed incursion on the territory of a sovereign nation is unacceptable."
