"Five jihadists were also killed," said Rami Abdel Rahman, director of the Britain-based monitoring group. Ansar al-Tawhid has ties to the larger Hurras al-Deen group, which is also active in the area of northwest Syria. Both are considered semi-officials franchises of Al-Qaeda in Syria. The area of Idlib and small parts of the adjacent provinces of Hama and Aleppo are mostly controlled by the rival Hayat Tahrir al-Sham organisation.
HTS is led by fighters who formerly belonged to Al-Qaeda's ex-affiliate in Syria. The attacks by Ansar al-Tawhid were carried out against regime positions in Masasna, a village in Hama province, the Observatory said.
