The UN Security Council has unanimously passed a vote on a conditional truce in Syria and demanded that all parties to the agreement fulfill their commitments to end fighting.
The council on Friday adopted a resolution drafted by the US and Russia that endorses the ceasefire deal and "demands that the cessation of hostilities to begin at midnight (Damascus time)" (22:00 GMT)."
UN Syria envoy Staffan de Mistura said the Syrian peace talks will reconvene on March 7, if the ceasefire holds.
"Assuming ... the cessation of hostilities largely holds, God willing, and the humanitarian access continue unabated, I intend to reconvene ... the intra-Syrian talks on Monday, March 7," de Mistura said.
Earlier on Friday, Syria's main opposition bloc said that almost 100 factions had agreed to respect a temporary truce, as air strikes by suspected Russian jets continued hitting rebel-held areas hours before the proposed ceasefire came into force.
The opposition alliance, known as the High Negotiations Committee (HNC), said in a statement that 97 factions and armed groups fighting the forces of President Bashar al-Assad will respect a two-week truce.

The HNC also demanded that Russia and Iran, Assad's main backers, also abide by the truce.
The Syrian government has previously said it would abide by the truce, but would have the right to retaliate for any attacks.
But later on Friday, Abu Mohammed al-Golani, the leader of al-Nusra, rejected the cessation of hostilities and called upon fighters to intensify attacks against Assad and his allies.

OPINION: A ceasefire in Syria is pure fantasy

In an audio message played on Orient News TV, al-Golani said that if Syria's war was not resolved, the consequences would spread to Sunni Muslims in other parts of the region, including the Arabian Peninsula.
"Fighters in Syria, willingly arm yourselves, intensify your attacks and have no fear of their troops and their aircraft," Golani added.

Meanwhile, Russian President Vladimir Putin said on Friday that the peace process in Syria would be "complicated" but that there were no other ways of ending the conflict.
He added, however, that his country's air force would continue its bombing campaign against ISIL, al-Nusra and other "terrorist groups" in Syria after the truce deal enters into force.
"The decisive fight against them will, without doubt, be continued," the Russian president said during a meeting of the FSB security service in Moscow.

Putin's comments came as the UK-based Syrian Observatory for Human Rights said that air strikes by suspected Russian warplanes were continuing to hit rebel-held positions on Friday hours before the deadline.
The rebel-held Damascus suburb of Douma was hit 40 times on Friday, the monitoring group said, along with other areas east of the capital, killing at least eight people, including three women and four children.
Mazen al-Shami, an activist based in the area, told the AFP news agency that the warplanes were Russian, adding that they carried out some 60 air raids on Friday. He said 25 strikes targeted Douma. "The air raids intensified after the revolutionary factions said they will abide by the ceasefire," al-Shami said via Skype.

Pact 'could end Syria's war'

On Thursday, US President Barack Obama said the proposed ceasefire could be a key step towards ending Syria's war.
Obama told a meeting of members of his National Security Council in Washington that halting air strikes was essential for the truce to be successful.
He added that ending fighting among various forces was the best route in tackling ISIL.

"The only way to deal with ISIL in a way that defeats them in a lasting way is to end the chaos in the civil war that has engulfed Syria," Obama said.
"That's how ISIL was able to thrive in the first place."
Obama noted, however, that it remains to be seen whether the "cessation of hostilities" will hold.
The deal marks the biggest diplomatic push yet to end Syria's nearly five-year-old war which has killed more than 260,000 people and displaced millions from their homes.
