They are not expanding East. Coming from Iraq and moving into Deir Ez Zour and then Palmyra it's basically the Mosul - Beirut suggested route [1] via Google Maps. They are at the doors of Aleppo and expanding in the suburbs of Damascus as we speak. The situation there is very serious. There are many economic refugees in this migratory wave but I don't believe many of them are from Syria. https://www.google.com/maps/dir/Mosul,+Iraq/Beirut,+Lebanon/@34.7069182,39.9449429,7.5z/data=!4m14!4m13!1m5!1m1!1s0x40079464db1a88b9:0x9745d74edd0f0930!2m2!1d43.1640004!2d36.3566484!1m5!1m1!1s0x151f17215880a78f:0x729182bae99836b4!2m2!1d35.4954794!2d33.8886289!5i1 https://www.google.com/maps/dir/Mosul,+Iraq/Beirut,+Lebanon/...
