Obama, EU leaders raise threat of new sanctions on Russia

US President Barack Obama and top European leaders urged Moscow to stop its "intimidation" of Ukraine and raised the prospect of fresh sanctions, France said Friday.

"The heads of state and government have called for a rapid reaction by the G7 and raised the prospect of new sanctions by the international community against Russia," the French presidency said in a statement.

Obama, along with German Chancellor Angela Merkel, British Prime Minister David Cameron, French President Francois Hollande and Italian Prime Minister Matteo Renzi also said it was "essential" for Ukraine's presidential election to go ahead as planned on May 25.
