AMMAN, Jordan — Forces battling the Islamic State (IS) in Syria seem to be putting a lot of effort into thwarting each other's strategies.
Syrian government troops, backed by allied Iraqi and Iranian militias, are bolstering their control along parts of the Syrian-Iraqi borders. Leaders of the Syrian armed opposition factions who spoke with Al-Monitor confirmed earlier reports that the Syrian government aims to create a land passageway from Iran though Iraq to Syria, to reach Syria's oil-rich Deir ez-Zor, which has been under IS control since 2014.
