German Chancellor Angela Merkel and French President Francois Hollande arrived in Moscow on Friday to discuss with President Vladimir Putin a last minute peace initiative for Ukraine, dpa reported. Before their departure to the Russian capital, both leaders cautioned that there was no guarantee of success. "We know it is completely open whether we'll manage to achieve a truce through these talks ... or if further talks will be required," Merkel said in Berlin. Hollande said that a ceasefire was only the first step toward a broader resolution to the conflict in eastern Ukraine. "We need to find a comprehensive solution," he said in Paris.
