The memorandum on de-escalation zones took effect on May 6.
"In general, the ceasefire is being adhered to. However, in some areas there have been local, unsubstantial clashes. It is impossible to solve everything in one day, but we hope that this [problem] will be eliminated," the source said on Saturday.
Representatives of the countries-guarantors of the truce in Syria (Russia, Iran, Turkey) signed on May 4 a memorandum on the creation of four zones of de-escalation in Syria, which include the province of Idlib and seven other regions. According to the memorandum, any clashes between the government forces and opposition armed groups must stop within the zones.
The war in Syria has been lasting for around six years with government troops fighting against numerous opposition factions and terror organizations such as al-Nusra Front and Daesh, outlawed in Russia.
The nationwide Syrian ceasefire regime was introduced on December 30, 2016. Terrorist organizations are not part of the ceasefire.
Russia's deputy defense minister said on May 5 that the implementation of the memorandum on de-escalation zones would put an end to the war.
