Reports of Russia's military presence have concerned leaders around the world, and on Saturday media said two Russian planes carrying aid landed in Latakia.
It took a while for Russian leaders to acknowledge reports the country is helping Syria beyond funding and humanitarian aid, but leaders confirmed Wednesday there are Russian advisers in the war-torn country after witnesses in Syria saw Russian ground troops.
A new video uploaded on YouTube appears to show the Russian soldiers in Syria.
US officials said they believed about 200 Russian naval infantrymen are stationed in Syria's coastal city of Latakia, the same regime stronghold that received Russian aid Saturday.
What seems to be certain is that Russian aid landed in Latakia safely, supporting the Syrian government. Here are photos of the plane that circulated on Twitter.
