Russian Forces Strike Syria's Southern Rebels In Preparation For Pro-Regime Ground Offensive
The strategy suggests Russia’s unprecedented attacks in the south are a precursor to a large-scale ground operation to retake a strategic area that borders both Jordan and Israeli-occupied Golan Heights.
On Wednesday, Russian planes struck the Tal Hara, Tal Antar, Kafr Nasaj and Aqraba neighborhoods of northern Daraa, according to the U.K.-based Syrian Observatory for Human Rights. Iran's state-run news agency claimed Russia’s targets were al Qaeda affiliate Jabhat al-Nusra militants.
Syrian Civil Defence, a volunteer rescue organization in Daraa, said airstrikes targeted civilian and rebel-held positions.
Regime ground forces and their allies are massing in the area in preparation to retake the Daraa triangle, an area of roughly 60 square kilometers that stretches southwest of the Syrian capital Damascus to southern Daraa city and back up to Quneitra in the Golan Heights.
Troops from the Syrian army’s 5th armored and 7th mechanized divisions along with fighters from the pro-regime National Defense Forces were deployed to Daraa’s northern countryside earlier this week, al-Masdar news reported.
Among Wednesday night’s bombardment were targets some 15 km from the Israeli-occupied Golan Heights and others on the border with Jordan.
A report from the Institute for the Study of War said if confirmed, Russian airstrikes "in southern Syria could be a sign of Russian cooperation with Israel and Jordan.
Jordan and Israel, two important American allies in the fight against ISIS, share borders with Syria’s southern provinces, potentially dragging them into the conflict if Russia persists with its bombardment of the south. Both countries, which backed the U.S. strategy to support moderate Syrian opposition groups, have already discussed military cooperation with Russia.
Last week, Russia and Jordan met and agreed to coordinate their operations in Syria through a "special working mechanism" in the Jordanian capital of Amman. Israeli Prime Minister Benjamin Netanyahu traveled to Moscow to discuss how the two countries could operate in Syria without getting in each other’s way.
