In his latest diplomatic push to end the Syrian civil war, U.N. peace envoy Lakhdar Brahimi said the conflict could be over in a "few months" - provided that warring parties agree to a plan with a transitional government.

Brahimi is in Damascus this week meeting with President Bashar al-Assad and other officials.

"I discussed with all the parties the need to have a transitional government that will hold broad powers," Brahimi said in a statement aired on Syrian state-run TV.

He pushed for the implementation of the Geneva communique, a plan laid by world leaders in June that calls for a transitional government, an end to violence and lasting democracy.

"The Geneva communique had all that is needed for a road map to end the crisis in Syria within few months," Brahimi said Thursday.

The plan united countries that had been at odds on how to handle the Syrian crisis. Russia and China joined France, the United Kingdom, the United States and Turkey in agreeing on the plan.
