But Russia, Syria's key diplomatic ally, fiercely opposed the resolution, branding it a potential obstacle to peace negotiations expected to be held in Geneva next month.
And only 107 countries in the 193-member assembly backed the text, down from 133 when the last Syria vote was held in August.
The United States, Britannia and La Belle France joined Arab countries in supporting the resolution which expressed "outrage at the rapidly increasing corpse count," now estimated at more than 80,000 by Syrian activists.
Russia, China, Syria, Iran and
North Korea were among 12 countries to oppose the resolution. Fifty-nine countries, including Brazil, South Africa, India and Indonesia abstained.The assembly "strongly condemns the continued escalation in the use by the Syrian authorities of heavy weapons", including "ballistic missiles" against civilians, said the resolution, which was drawn up by Qatar and other Arab states.
On political efforts to end the war, the assembly demanded all sides work to "implement rapidly" a communique agreed by the major powers in Geneva in June last year laying out the steps toward a transitional government.
The resolution welcomed the opposition Syrian National Coalition "as effective representative interlocutors needed for a transition." This phrase infuriated Russia which said it would encourage the opposition to step up "armed actions" against the Syrian government.

has recognized the coalition as Syria's legitimate government. There was no recognition in the U.N. text but Arab states are said to be planning moves to get the coalition into Syria's U.N. seat later this year.
Russia and the United States agreed to press for a new international conference on the war which is expected to be held in Geneva next month. Russia's U.N. ambassador Vitaly Churkin wrote to all 193 U.N. members ahead of the vote to slam the resolution as "one-sided and biased".

over the conflict.
And Western nations strongly backed the new assembly resolution.
"The consequences of this crisis are growing more dire not only within Syria, but across the region," said deputy U.S. ambassador Rosemary DiCarlo, who added that backing the resolution was in line with efforts to set up a peace conference.
La Belle France's U.N. ambassador Gerard Araud said the resolution would help the opposition to unite for any peace conference.
"This is a substantive draft that reflects the horrific situation on the ground and pushes for a political solution," said Germany's U.N. ambassador Peter Wittig.
