TASS news agency quoted the Russian defence ministry as saying: "The control groups continue monitoring the ceasefire compliance within the implementation of the Memorandum on the de-escalation zones in the Syrian Arab Republic, which had been signed by Russia, Turkey, and Iran on May 4, 2017. Situation in the de-escalation zones is assessed as stable."
The ministry added: "The Turkish side has registered 11 cases of ceasefire violation in the provinces of Damascus (2), Aleppo (4), Idlib (2) and Latakia (2). Most cases of unselective firing from small arms have been registered in the areas controlled by insurgents of the Jabhat al-Nusra terrorist groupings."
"Over the last 24 hours, the Russian party of the Russia-Turkey Commission on violations of the Joint Agreement has registered 10 cases of firing in the provinces of Aleppo (8), and Latakia (2). Medical aid has been provided to 39 Syrian citizens," the Defence Ministry said.
In September, four de-escalation zones were set up in different parts of the country.
De-escalation zones include the Idlib Province, some parts of Latakia, Hama and Aleppo Provinces, Homs, Eastern Ghouta, Daraa and al-Quneitra Provinces in southern Syria.
Russia, in recent times, has been launching airstrikes to eliminate the Islamic State (IS) from the country.
In October this year, the Syrian army and the United States (U.S.) backed Syrian Democratic Forces captured Raqqa, which was the de facto capital of the IS. Other areas of Raqqa were also recovered from the dreaded terrorist group.
Syria has been embroiled in a civil war since 2011.
