ASTANA (Sputnik) — Moscow works with Ankara to address these issues, he added.
"We also register movements from Turkish territory to the territory of Syria by members of illegal armed units… different cargoes and ammunition, armaments. We are conducting relevant work with the Turkish authorities to make them closely monitor that illegal flow of armaments for militants, which are delivered to the Syrian territory," Lavrentyev told reporters.
Earlier in the day, head of the government delegation Bashar Jaafari accused Turkey of violating the Syrian sovereignty and called on Ankara to close its borders for terrorists trying to enter Syria.
"A few dozens of armed groups, including those operating as part of the Southern Front, really want to join the process of hostilities cessation and express their readiness to sign the agreements. If this happens, it would really be a step forward," Lavrentyev said.
Russia and Turkey are guarantors of a nationwide Syrian ceasefire that came into force on December 30, and has been holding up in general, despite continued reports of violations. The UN Security Council passed a resolution in December supporting the effort.
