(AFP) - United States President Barack Obama urged greater efforts to end violence in war-torn Syria in brief talks with Russian President Vladimir Putin on Sunday, as concern mounted over a ferocious regime bombing campaign in rebel-held parts of Aleppo.
Obama made the comments to his Russian counterpart on the sidelines of an Asia-Pacific Economic Cooperation (APEC) summit in Peru, in what could be their last meeting before the US president leaves office in January.
