Air strikes on Syria’s northwestern Idlib region stopped on Saturday after the government agreed to a Russian-backed ceasefire.
Clashes between regime loyalists and insurgents have also ceased after a unilateral ceasefire by Syrian regime forces.
Syrian regime ally Russia announced that Damascus government forces would observe a new ceasefire from Saturday morning in Idlib, one of the last holdout of opposition to forces of Syrian President Bashar al-Assad.
The truce is the latest Russian-led effort to avert what the United Nations described as one of the worst humanitarian crisis in Syria’s the eight-year conflict.
Idlib region is home to some three million people.
According to the United Nations, bombardment by Damascus and Moscow since the end of April has displaced 400,000.
The war in Syria has killed more than 370,000 people and driven millions from their homes since it started.
Almost half of the displaced are living in camps or in the open air.
Most of the province and parts of neighbouring Aleppo and Latakia provinces are controlled by Hayat Tahrir al-Sham, an extrmist group related to Al-Qaeda.
Syrian President Bashar Al Assad controls around 60 per cent of the country.
