Russian Foreign Minister Sergei Lavrov said Monday that a political settlement of the conflict in Ukraine was possible only if the government in Kiev halted its military campaign against separatist rebels in the east, dpa reported. "As long as Kiev seeks a forceful solution, international efforts .. won't have success," Lavrov told reporters in Berlin, according to Russian news agencies. Lavrov added that four-party talks with his colleagues from Ukraine, Germany and France late on Sunday made no progress on the issue of a ceasefire, because the Ukrainians "keep making vague demands." It was unclear Monday if the talks would continue.
