>> reporter: good evening. the syrian opposition's immediate concern is a massacre in the city of homs which has been surrounded for over two weeks. it's been shelled from the outside. now the opposition worries that syrian troops will storm the center of the city. but the conflict in syria is no longer just a local affair. outside parties are becoming increasingly involved. russia, china, iran, hezbollah, iraqi shiite militia groups are all backing the syrian regime. russia has been arming the syrian government. the united states has been observing syria from drones, but u.s. officials say they don't see any clear options in this entrenched, bloody, proxy war .
