The Syrian army's declaration of cease-fire reflects an agreement reached Wednesday between Russian Federation and Turkey for a nationwide cease-fire in Syria, with both countries acting as guarantors to rein in their respective allies in the country.
Putin said in televised comments that Damascus and the "main forces of the armed opposition" had inked the truce agreement and a document expressing a readiness to start peace talks.
Washington is "100 percent behind the defeat and destruction of Daesh, even beyond Syria and Iraq", he said, according to RT.
"The battle against terrorist groups in Syria is just impeding the mission to liberate Beit-ul-Moqaddas from Israeli control", he said.
In a statement posted on the state-controlled Syrian Arab News Agency, the ministry said "terrorist organisations", including Islamic State and the country's al-Qaeda affiliate, Jabhat Fateh al-Sham, were not included in the ceasefire deal.
Putin also said he would reduce Moscow's military contingent in Syria, which has been flying a bombing campaign in support of President Bashar al-Assad since previous year.
"This agreement comes after Aleppo victory, so it reflects the trust of the Syrian state, and the army in the victory", he said, adding that "the liberation of Aleppo is not like before so we need to invest in that victory, and the first investment is in the cessation of hostilities". He said Russian Federation will continue "fighting worldwide terrorism in Syria" and supporting Assad's military.
Russian President Vladimir Putin said Friday he would now reduce Moscow's military contingent in Syria, which has been fighting to bolster the government since past year.
However, Russian Foreign Minister Sergei Lavrov said the United States could join the peace process once President-elect Donald Trump takes office.

Clashes and air strikes continued in some areas since the nationwide ceasefire, brokered by Russian Federation and Turkey began on Friday.
The powerful Islamist insurgent group Ahrar al-Sham meanwhile said it had not signed the ceasefire agreement because of "reservations", which it would make clear in due course.
Despite Erdogan's accusations, the USA has recognized Turkey's efforts in northern Syria, calling its efforts "very efficient, very successful".
The Syrian government had been shelling the area before the truce began at midnight as it pushes rebels there to accept a "reconciliation deal" and leave.
But it reportedly does cover the rebel-held Eastern Ghouta area near Damascus, which had been a sticking-point in negotiations.
The Moscow-Ankara proposal is said to take effect at midnight local time on Thursday, December 29 (22:00 GMT Wednesday), the Anadolu news service said citing anonymous sources.
Reuters reported that an outline for the comprehensive deal had already been drawn up Russia, Turkey, and Iran and involved dividing Syria into informal zones of regional power influences and allowing Bashar al-Assad to remain in power for at least several years.
