To NATO: "If Russia intervenes in eastern Ukraine would be a historic mistake"

Pro-Russian separatists who took a local government building in the city of Donetsk, in eastern Ukraine, Monday proclaimed independent region in an event that echoes the Russian annexation of Crimea

The general secretary of NATO, Anders Fogh Rasmussen, warned Russia that "any further movement in eastern Ukraine represent a serious escalation" in the conflict after annexation of Crimea. He also said that "events in eastern Ukraine are a major concern."

"If Russia additionally intervene in Ukraine would be a historic mistake. Would have serious consequences for our relationship," the Dane has warned in a press conference in Paris, where he pointed out that the Allies are now "reviewing" these relations after cutting all bilateral practical cooperation in response to the annexation of the Crimea and the Foreign Ministers of NATO will make decisions about in June based on "the situation in Ukraine and the behavior of Russia."

Recall that U.S. President Barack Obama, has already ruled out any military intervention.

"I ask Russia to step back. Any further movement in eastern Ukraine represent a serious escalation" Rasmussen said in a speech at a seminar on the transformation of NATO in Paris.

"We do call on Russia to withdraw its tens of thousands of troops amassed on the borders of Ukraine, is involved in a genuine dialogue with the Ukrainian authorities and abide by their international commitments," he concluded.
