On Sunday, the ministry reported that the Russian side of the Russian-Turkish commission monitoring the implementation of the Syrian truce had recorded one ceasefire violation in the country over the past 24 hours, while the Turkish side had registered no truce breaches.
"One shelling by the Jabhat Al-Nusra* terrorist organization was recorded in the settlement of Karsaa in Idlib province", Rear Admiral Oleg Zhuravlev said at a briefing on Sunday.
At the same time, no shelling by illegal armed groups controlled by Turkey has been recorded over the past 24 hours, he added.
On 5 March, Russian President Vladimir Putin and his Turkish counterpart, Recep Tayyip Erdogan, agreed on a ceasefire in Idlib, which started at midnight. The sides also agreed to create a security corridor six kilometres (3.7 miles) north and south of the M4 highway in Syria, which connects the provinces of Latakia and Aleppo.
Under the ceasefire agreement, Moscow and Ankara conduct joint patrols along the M4 highway, which is currently controlled by militants.
Militants remain in control of a small pocket of the Idlib province in northwest Syria.
*Hayat Tahrir al-Sham (formerly known as Jabhat al-Nusra) is a terrorist organization banned in Russia and many other countries.
