The warplanes carried out several rounds of combat flights over the positions and movements of Tahrir al-Sham in Jisr al-Shughour, Ariha, Jabal al-Zawiyeh, Jabal al-Araba'een, al-Sukriyeh, al-Qasaniyeh and Halouz region in Southwestern Idlib, killing an unspecified number of militants and destroying their equipment.
A local source said that an underground base of Tahrir al-Sham was destroyed in the air raids in Jabal al-Zawiyeh region, adding that the militants sustained at least a dozen casualties in the incident.
In a relevant development on Saturday the Russian army aircraft launched a heavy barrage of airstrikes over the positions of Tahrir al-Sham Hay'at near the key town of Jisr al-Shughour near Lattakia-Turkey border.
The fighter jets conducted over 30 airstrikes over Idlib province.
In addition to targeting Jisr al-Shughour, the warplanes also struck a Shari’ah (religious) Court of the Tahrir al-Sham near the town of al-Dana.
The airstrikes came after reports that the militants in Idlib were preparing to launch an offensive against the Syrian Army in the region.
