BEIRUT — Russia and the United Nations called Thursday for the resuscitation of a peace initiative for Syria that never got off the ground when it was proposed months ago because both parties to the conflict rejected it.
The plan, unveiled by world powers at an international conference in Geneva in June, called for an open-ended cease-fire, a transitional government to run the country until elections, and the drafting of a new constitution.
The plan was a non-starter for the opposition because it did not explicitly ban authoritarian President Bashar Assad and other members of his regime from taking part in the transitional leadership. The regime ignored it because it would entail voluntarily giving up power.
There is no sign that the plan has any more chance of succeeding now than it did back in June. Mr. Assad's government did not comment on the attempt to revive the proposal, and a coordinator for the rebels seeking to end Mr. Assad's rule called the plan "illogical."
"No one in the opposition can accept this, and if they accept it, it will be refused by the Syrian people," said Bassam Al-Dada, a Turkey-based coordinator with the rebel Free Syrian Army.
He said Mr. Assad's forces have killed too many people for him to play a role in any solution. Anti-regime activists say more than 40,000 people have been killed since the revolt against Assad began in March 2011.
Because of Russian objections, the original plan did not call specifically for Mr. Assad's ouster or ban him or top members of his regime from participating in the new government.
Much has changed in Syria since the plan was first presented. Rebels have gained momentum, seizing more territory and several military installations in the country's north. They also are expanding their control in suburbs of the capital, Damascus.
These gains make it increasingly unlikely that they will accept any plan that allows any part of Mr. Assad's regime to remain.
The government, too, has given no indication it will give any ground and dismisses almost all opposition activities as terrorism that seeks to destroy the country.
In Damascus on Thursday, the U.N. envoy for Syria Lakhdar Brahimi called the Geneva plan "suitable enough" to end Syria's war.
"The Syrian people seek genuine change," Mr. Brahimi said, adding that the transitional period "must not lead to the collapse of the state or the state's institutions."
Mr. Brahimi said that original plan could be amended, but he didn't say how. He did not mention Mr. Assad by name and only said the transitional government would have "full executive powers," meaning "all the authority of the state should be possessed by that government."
Mr. Brahimi said it remains to be determined what kind of government would follow and whether the elections called for under the plan would be for president or parliament.
In Moscow, Foreign Ministry spokesman Alexander Lukashevich said Russia, too, is trying to revive the Geneva plan.
"We continue to believe that there is no alternative to that document in trying to find a settlement in Syria," Mr. Lukashevich said. He also reaffirmed Moscow's objection to calls for Mr. Assad's ouster.
Russia has been Mr. Assad's strongest backer throughout the conflict, selling arms to his forces and, along with China, protecting him from censure by the U.N. Security Council for his violent crackdown on the opposition.
Top Russian officials recently have signaled a new resignation to the idea that Mr. Assad could fall. Still, they have said they will not call for his ouster or offer him refuge should he decide to flee.
