President Putin has said he would reduce Moscow's military contingent in Syria, which has been fighting for the government since 2016.
Beirut: A ceasefire held across most of Syria on Saturday as Russia and Turkey secured unanimous passage of a UN resolution backing their efforts to "jumpstart" talks aimed at ending the nearly six-year conflict.
The Security Council resolution aims to pave the way for talks in January in the Kazakhstan capital of Astana, under the aegis of Russia and Iran, both Syrian government supporters, and of rebel backer Turkey.
Turkey and Russia say the Astana talks will supplement, not replace, UN-backed peace efforts, including talks set to resume February 8 in Geneva.
The text of the UN measure "welcomes and supports the efforts by Russia and Turkey to end violence in Syria and jumpstart a political process" and it calls the Astana talks "an important step" ahead of the upcoming Geneva negotiations.
It also calls for the "rapid, safe and unhindered" delivery of humanitarian aid in Syria.
Russia and Turkey brokered the current ceasefire and, while backing opposing forces in the conflict, have been working increasingly closely on Syria, including to allow evacuations from the besieged city of Aleppo.
Washington has been conspicuously absent from the new process but has called the truce "positive." Moscow has said it hoped to bring US President-elect Donald Trump's administration on board once he takes office in January.
Truce largely holds
Russia's UN ambassador Vitaly Churkin had earlier voiced hope the Security Council would endorse the planned talks in Kazakhstan and back the resolution unanimously.
But several council members had demanded clarifications over the reach of the resolution, what it would mean for the UN talks, how it might affect rebels recently ousted from Aleppo, and what it would mean for humanitarian aid.
The Syrian Observatory for Human Rights, a British-based monitor of the war, said Saturday that most of Syria remained calm, despite limited clashes.
The government in Damascus called the ceasefire a "real opportunity" to find a political solution to a war that has claimed more than 310,000 lives and displaced millions since it began in March 2011 with protests against the regime of President Bashar al-Assad.
Limited clashes continued in some parts of Syria on Saturday, including around Wadi Barada near Damascus, and the southern city of Daraa, where one opposition fighter was killed.
The fighting in Wadi Barada has led to water shortages that have affected four million people in the capital.
Five rebel fighters and two civilians have been killed in Wadi Barada and the rebel bastion of Eastern Ghouta near Damascus since the truce started on Friday, said Syrian Observatory director Rami Abdel Rahman.
The Observatory said a total of 60,000 people were killed in violence across Syria in 2016, more than 13,000 of them civilians.
The forces in Wadi Barada include Fateh al-Sham Front, previously known as Al-Nusra Front. That group and the Islamic State group are excluded from the truce.
Iran urges 'vigilance'
Syrian Foreign Minister Walid Muallem held talks in key ally Iran Saturday with President Hassan Rouhani and the Supreme National Security Council secretary Ali Shamkhani.
Rouhani said "vigilance" was needed to ensure that the rebels not reorganize.
The official IRNA news agency also quoted Shamkhani as warning that any poitical solution to the Syria conflict must not lead to "the weakening" of the Damascus government.
Russian President Vladimir Putin has said he would reduce Moscow's military contingent in Syria, which has been fighting to bolster the government since 2016.
But he added Russia would continue to fight "terrorism" and maintain its support for Assad's government.
