Syrian civil war: Five hundred members of the Syrian Democratic Forces (SDF) are airlifted south of the Euphrates by United States Air Force helicopters, beginning the Battle of Tabqa.

The Syrian civil war began with the Syrian revolution in March 2011, when popular discontent with the Ba'athist regime ruled by Bashar al-Assad triggered large-scale protests and pro-democracy rallies across Syria, as part of the wider Arab Spring. The Assad regime responded to the protests with lethal force, sparking a civil war. The Syrian revolution lasted almost 14 years and culminated in the fall of the Assad regime in December 2024. Many sources regard this as the end of the civil war.

The Syrian Democratic Forces (SDF) is a Kurdish-led coalition of U.S.-backed left-wing ethnic militias and rebel groups, and serves as the official military wing of the Democratic Autonomous Administration of North and East Syria. Founded on 10 October 2015, the stated mission of the SDF is to create a secular, democratic, and federalized Syria. The SDF is opposed by Turkey, who view the group as an extension of the Kurdistan Workers' Party (PKK), which it has designated a terrorist group. On 10 March 2025, the SDF agreed to integrate into Syrian state institutions under the Syrian caretaker government. Mazloum Abdi met with the committee formed by Ahmed al-Sharaa to implement the deal; further meetings were planned for April.

The Euphrates is the longest and one of the most historically important rivers of West Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia. Originating in Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab in Iraq, which empties into the Persian Gulf.

The United States Air Force (USAF) is the air service branch of the United States Department of Defense. It is one of the six United States Armed Forces and one of the eight uniformed services of the United States. Tracing its origins to 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established by transfer of personnel from the Army Air Forces with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control.
