Turkey is taking necessary measures along its 150 km (90 mile) border with the Syrian province of Idlib, Prime Minister Binali Yıldırım said on Friday.
Yıldırım was speaking a day after Turkey's customs minister said Turkish authorities will limit movement of non-humanitarian goods at the Bab al-Hawa border crossing into Idlib because the Syrian side is controlled by a "terrorist organisation".
President Recep Tayyip Erdoğan said on Friday the border crossing would be kept open for humanitarian aid but weapons would not be allowed across.
