Syria conflict: 'Good beginning' to peace talks

Syria's opposition and government have met twice in what the UN's Lakhdar Brahimi said was "a good beginning" to peace talks.
He said getting an aid convoy into Homs had been discussed, and the matter of detainees would be the focus of Sunday's talks.
The Syrian National Coalition say they will start discussions on a transitional government on Monday - a subject upon which the delegations strongly disagree, and which could damage the talks.
