The US-backed Syrian Democratic Forces capture the town of Baghuz in Eastern Syria, declaring military victory over the Islamic State of Iraq and the Levant after four years of fighting, although the group maintains a scattered presence and sleeper cells across Syria and Iraq.

The Battle of Baghuz Fawqani was an offensive by the Syrian Democratic Forces (SDF), assisted by Combined Joint Task Force – Operation Inherent Resolve (CJTF-OIR) coalition airstrikes, artillery, and special forces personnel, that began on 9 February 2019 as part of the Deir ez-Zor campaign of the Syrian Civil War. The battle—which was composed of a series of ground assaults—took place in and around the Syrian town of Al-Baghuz Fawqani in the Middle Euphrates River Valley near the Iraq–Syria border, and was the territorial last stand of the Islamic State (IS) in eastern Syria.

Al-Baghuz Fawqani is a town in Syria, located in Abu Kamal District, Deir ez-Zor. According to the Syria Central Bureau of Statistics (CBS), Al-Baghuz Fawqani had a population of 10,649 in the 2004 census.

The Islamic State (IS), also known as the Islamic State of Iraq and the Levant (ISIL), the Islamic State of Iraq and Syria (ISIS) and Daesh, is a transnational Salafi jihadist militant organisation and was a unrecognised quasi-state. IS occupied significant territory in Iraq and Syria in 2013, but lost most of it in 2017 and 2019. In 2014, the group proclaimed itself to be a worldwide caliphate, and claimed religious and political authority over all Muslims worldwide, a claim not accepted by the vast majority of Muslims. It is designated as a terrorist organisation by the United Nations and many countries around the world, including Muslim countries.
