AKIPRESS.COM - World leaders are due to meet Ukraine's President before the NATO summit gets under way in Wales.

President Petro Poroshenko will update the U.S. and EU leaders after discussions with Russia's President Vladimir Putin, BBC reports.

France has ramped up the pressure on Mr Putin by axing its contract to deliver two navy assault ships to Russia.

The two-day NATO summit is expected to be dominated by the crisis in Ukraine, but leaders will also discuss the rise of Islamic State, and Afghanistan.

Mr. Poroshenko will brief UK PM David Cameron, U.S. President Barack Obama and the leaders of France, Italy and Germany, in what correspondents say is a clear show of support to Ukraine's leader.
