Russian President Vladimir Putin met Saudi Arabia's defence minister on Sunday, in Moscow's biggest attempt so far to reach out to enemies of Syria's President Bashar al-Assad since Russia joined the conflict with air strikes. Putin met Sheikh Mohammed bin Salman, a son of the Saudi king, on the sidelines of a Formula One race on Sunday, nearly two weeks since Moscow began bombing enemies of Assad, including rebel groups that are supported by Riyadh. Saudi Arabia's Foreign Minister Adel al-Jubeir, appearing alongside Russia's Sergei Lavrov, said Riyadh had concerns about Russia's policy. Lavrov said Moscow understood Saudi concerns and the two countries shared the aim of preventing the establishment of a terrorist caliphate in Syria. http://english.ahram.org.eg/News/152723.aspx
