The Turkish forces renewed shelling on Syrian army positions in the western countryside of Idlib province in northwestern Syria on Saturday, a war monitor reported.
The shelling was fired by the Turkish forces positioned on Syrian-Turkish border and targeted areas in the western countryside of Idlib province, said the Syrian Observatory for Human Rights.
The Turkey-backed rebel groups also shot down a reconnaissance plane in the Jabal al-Zawiyeh area in the southern countryside of Idlib, the Britain-based watchdog group added.
On the other side, the Syrian and Russian warplanes carried out around 75 shelling on rebel-held areas in the Jabal al-Zawiyeh area.
Earlier in the day, the observatory said as many as 2,700 Turkish military vehicles have been sent into Syria over the past 19 days, as part of the Turkish tactic to send military equipment to Idlib and the northern Syrian province of Aleppo.
Additionally, over 7,400 Turkish soldiers have been deployed in Idlib and Aleppo in the same period, said the observatory.
The deployment of Turkish soldiers and vehicles comes as part of the Turkish plan to halt the progress of the Syrian army in the countryside of Idlib, the last major rebel stronghold in Syria.
