French President Francois Hollande says he and German Chancellor Angela Merkel are heading to Ukraine with a new peace initiative.

Speaking at a news conference in Paris and describing the Ukrainian conflict as a war, Hollande said the two will go to Kiev on Thursday and then head to Moscow the following day with a proposal "based on the territorial integrity of Ukraine."

U.S. Secretary of State John Kerry is also in Ukraine, to show support for the government amid a fast-moving flurry of international diplomacy.
