Syrian President Bashar Assad arrived in Moscow on Tuesday, where he is scheduled to meet top ally Russian President Vladimir Putin.
Russia is a main backer of Assad and has a broad presence in Syria, where a 12-year uprising-turned-civil war has killed nearly half a million people and displaced half the country’s pre-war population. Moscow has played a pivotal role in fighting back armed opposition groups trying to topple Assad’s government through its military support, and has also aggressively backed Damascus against opponents at the United Nations.
