UNITED NATIONS — The U.N. Security Council voted unanimously Friday night to secure and destroy Syria's chemical weapons stockpile, a landmark decision aimed at taking poison gas off the battlefield in the escalating 2 1/2-year conflict.
The vote after two weeks of intense negotiations marked a major breakthrough in the paralysis that has gripped the council since the Syrian uprising began. Russia and China previously vetoed three Western-backed resolutions pressuring President Bashar Assad's regime to end the violence.

"Today's historic resolution is the first hopeful news on Syria in a long time," U.N. Secretary-General Ban Ki-moon told the council immediately after the vote, but he and others stressed that much more needs to be done to stop the fighting that has left more 100,000 dead.
"A red light for one form of weapons does not mean a green light for others," the U.N. chief said. "This is not a license to kill with conventional weapons."
U.S. Secretary of State John Kerry said the "strong, enforceable, precedent-setting" resolution shows that diplomacy can be so powerful "that it can peacefully defuse the worst weapons of war."
Russian Foreign Minister Sergey Lavrov stressed that the resolution does not automatically impose sanctions on Syria. The resolution calls for consequences if Syria fails to comply, but those will depend on the council passing another resolution in the event of non-compliance. That will give Assad ally Russia the means to stop any punishment from being imposed.
As a sign of the broad support for the resolution, all 15 council members signed on as co-sponsors.
For the first time, the council endorsed the road map for a political transition in Syria adopted by key nations in June 2012 and called for an international conference to be convened "as soon as possible" to implement it.
Ban said the target date for a new peace conference in Geneva is mid-November.
Whether the council can remain united to press for an end to the conflict remains to be seen.
"We know despite its clear usefulness, one resolution alone will not save Syria," France's Foreign Minister Laurent Fabius said after the vote.
Syria's U.N. Ambassador Bashar Ja'afari accused unnamed nations of already giving the resolution a negative interpretation and trying to "derail it from its lofty purposes."
And Republican Sens. John McCain and Lindsey Graham, who have been harshly critical of Obama's policy on Syria, dismissed the resolution as "another triumph of hope over reality." It "contains no meaningful or immediate enforcement mechanisms, let alone a threat of the use of force for the Assad regime's non-compliance," they said in a statement that was highly skeptical that Russia would ever approve a threat of force for non-compliance.
The vote came just hours after the world's chemical weapons watchdog adopted a U.S.-Russian plan that lays out benchmarks and timelines for cataloging, quarantining and ultimately destroying Syria's chemical weapons, their precursors and delivery systems.
The Security Council resolution enshrines the plan approved by Organization for the Prohibition of Chemical Weapons, making it legally binding.
