2018 Southern Syria offensive

The 2018 Southern Syria offensive, code-named Operation Basalt (Arabic: عملية البازلت), was a military operation launched by the Syrian Arab Army (SAA) and its allies against the rebels and ISIL in Southern Syria. The fighting began with a surprise attack on rebel-held areas in the eastern part of the Daraa Governorate in an attempt to fracture rebel-held lines and weaken morale, ahead of their offensive in the greater Southern Syria region.
