The cessation of hostilities that went into effect at midnight local time appears to be holding in areas across Syria, despite a few reports of clashes between pro-regime and opposition groups. The ceasefire is seen as the first major pause in fighting in the country in the five-year civil war.
The agreement, brokered by the United States and Russia and backed by the United Nations Security Council, involves forces loyal to Syrian President Bashar al-Assad and the rebel groups that are fighting his regime. Two groups excluded from the agreement are the Nusra Front and Islamic State (IS), which the Syrian government and its Russian backers vowed to continue to fight. The United States and its international coalition are also fighting IS in Syria and in neighboring Iraq.
For the first time in several months, Russia has largely stopped its airstrikes, despite launching a barrage of airstrikes in the lead up to the ceasefire.
Despite the calm, both sides claimed breaches of the agreement had occurred.
Rebel groups claimed they came under attack from government ground forces in northwestern Syria.
Syria state TV also reported that several shells had hit residential areas of Damascus.
If the ceasefire holds, the United Nations envoy for Syria, Staffan de Mistura, said that peace talks could resume on March 7 in order to find a more durable solution to the conflict that has killed over 250,000 people since 2011.
