Mediators blame Ukraine rebels over talks

International mediators have accused pro-Russian separatists in eastern Ukraine of lacking willingness to reach a truce with the government. The Organisation for Security and Cooperation in Europe (OSCE) spoke out after a planned video conference call failed to take place on Tuesday. Fighting continues, with the government saying six soldiers died overnight. EU leaders are expected to expand sanctions against Russia at their summit in Brussels on Wednesday.
