Putin and Obama discuss Ukraine's peace plan

Russian President Vladimir Putin discussed proposals for peace in Ukraine with the US President Barack Obama today, the Kremlin said in a statement.

Speaking on the phone, the two leaders discussed the Ukrainian military ceasefire that was declared by President Petro Poroshenko last week.

Mr Obama urged Mr Putin to support the peace plan and said Moscow would face further "costs" if it did not take steps to reduce tensions in the country, the White House said.
