Russia must pay a price for its actions in Ukraine, says US President Barack Obama, hours ahead of talks in The Hague with his Group of Seven (G7) counterparts, according to dap. "Europe and America are united in our support of the Ukrainian government and the Ukrainian people," Obama said, after talks with Dutch Prime Minister Mark Rutte. "We are united in imposing a cost on Russia for its actions so far." "We both regard Russia's attempts to annex the Crimea as a flagrant breach of international law, and we condemn its actions in the strongest possible terms," Rutte said. The presence of 53 world leaders at a Nuclear Security Summit in The Hague was an "important opportunity" to discuss developments in Ukraine, he added.
