PARIS (AFP) – Presidents Francois Hollande of France and Barack Obama of the United States on Saturday warned of “new measures” against Russia if it fails to make progress on defusing the crisis in Ukraine, the French presidency said.

In a phone call on Saturday, Hollande and Obama insisted on the “need for Russia to withdraw forces sent to Crimea since the end of February and to do everything to allow the deployment of international observers,” it said.
