But Syria is unlikely to accept the latest effort to end the nearly year-long uprising.
Saudi Arabian Foreign Minister Saud Al-Faisal expressed the League's frustration with Syria, telling delegates it was no longer appropriate for the league to act as bystanders to Syrian bloodshed.
"Until when will we remain spectators?" he said. "It is a disgrace for us as Muslims and Arabs to accept" the bloodshed in Syria, he said.
In the meantime, the head of al-Qaida is calling on Muslims around the world to support Syrian rebels seeking to overthrow President Bashar Assad, and it appears to be already happening.
A senior Iraqi official said intelligence over the last four months has revealed a flow of al-Qaida linked fighters from Iraq into Syria.
