A senior U.S. official says the top American and Russian diplomats will hold a surprise meeting with the U.N. peace envoy for Syria, signaling fresh hopes of an international breakthrough to end the Arab country's 21-month civil war.
U.S. Secretary of State Hillary Rodham Clinton, Russian Foreign Minister Sergey Lavrov and mediator Lakhdar Brahimi will meet Thursday in Dublin.
The official spoke on condition of anonymity because she wasn't authorized to talk publicly on the matter.
The former Cold War foes have fought bitterly over how to address Syria's conflict.
But the gathering of the three key international figures suggests possible compromise in the offing, and confirms talk of an easing of some of the acrimony that's raged between Moscow and Washington over how to handle Syria's violence.
