The Syrian government is holding a referendum on a new constitution as violence continues around the country, killing at least 30 people.
The new constitution calls for a multi-party parliamentary election within three months. The opposition has boycotted the vote, calling it a farce and demanding President Bashar al-Assad stand down.
US Secretary of State Hillary Clinton has said there is strong possibility Syria could descend into civil war. But she warned that intervention from outsiders could exacerbate the situation
