Raqqa campaign (2016–2017)

The Raqqa campaign (codenamed Operation Wrath of Euphrates) was a military operation launched in November 2016 during the Rojava–Islamist conflict by the Syrian Democratic Forces (SDF) against the Islamic State (IS) in the Raqqa Governorate, with the goal of isolating and eventually capturing the Islamic State's capital city, Raqqa. The SDF's subsidiary goals included capturing the Tabqa Dam, the nearby city of al-Thawrah, and the Mansoura Dam further downstream.
