Top news: Syrian rebel groups began negotiations in Doha over forming a united political front. The talks come shortly after U.S. Secretary of State Hillary Clinton suggested that the Syrian National Council has outlived its usefulness and should be integrated into a larger umbrella opposition group which would allow greater coordination between fighters in Syria, exile groups, and the opposition's foreign backers.

The SNC, which has been frequently consumed by infighting over the course of the campaign against Bashar al-Assad's government, is attempting to reform itself to become more exclusive in order to head off a challenge from the new U.S.-backed coalition, the Syrian National Initiative. Expectations that the meeting will end in a successful resolution are low.

Meanwhile, back in Syria, a massive bombing hit near an Army compound in Damascus. Opposition activists say the bombing was likely the work of the Ahfad al-Rasoul Brigade, an Islamist militant group. Rebels also captured an oil field in Eastern Syria on Sunday.  

Opposition groups say government forces killed 179 people on Sunday, including 20 children, mostly by shelling the suburbs of Damascus.
