BEIRUT - International mediator Lakhdar Brahimi said on Wednesday that Syria's civil war risked spreading across borders into an "all-consuming" conflict unless it was eventually addressed.

Brahimi, speaking after talks in Beirut, said he hoped this month's Islamic holiday of Eid al-Adha offered a chance for both sides to cease fire and warned that the Middle East would suffer unless the violence was contained.

"This crisis cannot remain within Syrian borders indefinitely. Either it will be addressed or it will increase ... and be all-consuming," he said.
