Tahrir al-Sham in the context of "Palmyra offensive (2024)"

On 7 December 2024, the Syrian opposition group known as the Southern Operations Room, in co-ordination with the Military Operations Command, led forces that entered the Rif Dimashq region of Syria from the south, and those forces then came within 20 kilometres (12 mi) of the capital Damascus. The Syrian Army withdrew from multiple points in the outskirts. Concurrently with the advance towards Damascus, opposition militia Tahrir al-Sham and the Turkish-backed Syrian National Army in the north launched an offensive into Homs, while the Syrian Free Army advanced into the capital from the southeast. By 8 December 2024, rebel forces entered the city's Barzeh neighborhood. According to official state reports in Russian mass media and media footage, President Bashar al-Assad left Damascus by air to Moscow, where he was granted asylum, sealing the fall of his regime.

Harakat Ahrar al-Sham al-Islamiyya (Arabic: حركة أحرار الشام الإسلامية, romanized: Ḥarakat Aḥrār aš-Šām al-Islāmiyah, lit. 'Islamic Movement of the Freemen of the Levant'), commonly referred to as Ahrar al-Sham, was a coalition of multiple Sunni Islamist units that coalesced into a single brigade and later a division in order to fight against the Ba'athist regime led by Bashar al-Assad during the Syrian Civil War. Ahrar al-Sham was led by Hassan Aboud until his death in 2014. In July 2013, Ahrar al-Sham had 10,000 to 20,000 fighters, which at the time made it the second most powerful unit fighting against al-Assad, after the Free Syrian Army. It was the principal organization operating under the umbrella of the Syrian Islamic Front and was a major component of the Islamic Front. With an estimated 20,000 fighters in 2015, Ahrar al-Sham became the largest rebel group in Syria after the Free Syrian Army became less powerful. Ahrar al-Sham and Jaysh al-Islam were the main rebel groups supported by Turkey.On 18 February 2018, Ahrar al-Sham merged with the Nour al-Din al-Zenki Movement to form the Syrian Liberation Front.

The group aims to create an Islamic state under Sharia law. While both are major rebel groups, Ahrar al-Sham is not to be confused with Tahrir al-Sham, its main rival and former ally. Before 2016, Ahrar al-Sham allied with the al-Nusra Front, a now-defunct affiliate of al-Qaeda. From 2017 onward, it increasingly fought against Tahrir al-Sham, an Islamic coalition formed under the initiative of a former Ahrar leader, Abu Jaber Sheikh; through a merger of Ahrar al-Sham's Jaysh al-Ahrar faction, Jabhat Fatah al-Sham, Nur al-Din Zenki and other militia groups.
