But an opposition figure described the award as "a premature step" that will allegedly divert attention from the "real cause" of the country's bloodshed the regime in Damascus.
Both spoke hours after the announcement in Oslo that The Hague-based Organisation for the Prohibition of Chemical Weapons won the Nobel Peace Prize for working to eliminate the scourge that has haunted generations from World War I to the battlefields of Syria.
Their task is unprecedented, the UN has mandated the OPCW to rid Syria of its 1,000-ton stockpile of chemical weapons by mid-2014.
It's the tightest deadline ever given to the organisation and also the first conducted amid ongoing fighting.

Syria's conflict, which erupted in March 2011, has pitted disorganised armed rebels against forces loyal to the regime of President Bashar Assad.
The inspectors' mission stems from a deadly August 21 attack on opposition-held suburbs of Damascus in which the UN has determined the nerve agent sarin was used.
Fayez Sayegh, a lawmaker and member of Assad's ruling Baath party, told The Associated Press that by allowing the inspectors in, Syria is "giving an example to countries that have chemical and nuclear weapons."
He said the OPCW should work to rid the entire Middle East, including Israel, of weapons of mass destruction.
But Louay Safi, a senior figure in Syria's main opposition bloc, warned that giving the Nobel prize to the OPCW was too premature.
"If this prize gives the impression that the chemical weapons inspections in Syria will help foster peace, then it's a wrong perception," Safi, who serves as a political strategist for the Western-backed Syrian National Coalition, told the AP over the phone from Qatar.
