The Bab al-Hawa Border Crossing is located on the Syria–Turkey border about 50 km (31 mi) west of Aleppo in northwest Syria. It connects the Syrian M45 and the Turkish D827 highways, between the cities of İskenderun and Idlib, and is known for its long lines of trucks and buses. The closest town on the Turkish side of the border is Reyhanlı in Hatay Province, and the closest towns on the Syrian side are ad-Dana and Atarib. The crossing is the site of a 6th-century triumphal arch. It has been an important crossing for Syrian rebels during the Syrian civil war.

Hay'at Tahrir al-Sham, commonly referred to as Tahrir al-Sham, is a Sunni Islamist political and armed organisation involved in the Syrian Civil War. It was formed on 28 January 2017 as a merger between Jaysh al-Ahrar, Jabhat Fateh al-Sham (JFS), Ansar al-Din Front, Jaysh al-Sunna, Liwa al-Haqq, and Nour al-Din al-Zenki Movement. The unification process was held under the initiative of Abu Jaber Shaykh, an Islamist commander who had been the second Emir of Ahrar al-Sham.
