The decision by Russia and Turkey on Idlib is an intermediate step; the demilitarized zone will prevent the shelling of Syrian troops at Hmeymim base, Russian Foreign Minister Sergei Lavrov said, according to Sputnik.

"As for the Russian-Turkish agreement on Idlib, it is aimed primarily at eradicating the terrorist threat. This is certainly an intermediate step, because only a demilitarized zone is being created," Lavrov said.

According to him, this is a necessary step, as it will prevent shelling from the de-escalation zone in Idlib on the positions of Syrian troops and the Russian military base in Hmeymim.

Previously, Russian President Vladimir Putin and his Turkish counterpart Recep Tayyip Erdogan held a meeting in Russia's Black Sea resort of Sochi, during which they have agreed to set up a demilitarized zone in Idlib by October 15.

The city of Idlib is the last remaining stronghold of anti-government insurgents and al-Qaeda-linked terror groups in Syria.
