Russia said Saturday that it will step up air strikes in Syria. “We will not only continue strikes…We will also increase their intensity,” said Andrei Kartapolov, a General Staff member of the Russian Army. Russian jets have already carried out over 60 sorties in 72 hours in Syria. U.S. President Obama warned Russian President Vladimir Putin Friday that he was defending a losing authoritarian ally and could be sucked into a “quagmire.”
