According to the Syria Central Bureau of Statistics (CBS), Sinjar had a population of 2583 in the 2004 census.

Later, Jabhat al-Nusra, which later became Tahrir al-Sham in January 2017 came to control the town.

Villagers there protested against Nusra's control due to local disagreements.

Al Nusra was supported by Lebanese Christian leader Dr. Samir Geagea.

The village of Sinjar was captured by the Syrian Arab Army from Tahrir al-Sham forces during the Northwestern Syria offensive in January 2018.
