Syria conflict: BBC on Homs aid effort
The BBC's Lyse Doucet is reporting from the besieged Syrian city of Homs.
UN and Red Crescent workers have been delivering aid and have evacuated more civilians after a day of sensitive negotiations.
The forces of Syrian President Bashar al-Assad have been besieging rebel-held areas of Homs for 18 months.
Our correspondent has been tweeting throughout the operation and filing reports in video.

Operations were suspended on Tuesday because of what UN and Syrian officials said were logistical reasons. More than 1,000 civilians are believed to remain in besieged rebel-held areas of the Old City.
Some pro-government forces are vehemently opposed to an operation that is allowing fighters to escape an area that has been the focus of heavy fighting for nearly two years, our correspondent says. And the opposition is angry that young men who leave Homs are being taken in for questioning.
Earlier in the week, the UN's humanitarian chief sharply criticised the two sides in the conflict, saying UN and Syrian Red Crescent workers were "deliberately targeted" as they tried to deliver aid.
UN agencies have also expressed concern over the fate of dozens of men who were taken in by Syrian security personnel after they fled Homs.
Yacoub el-Hillo, the UN's humanitarian co-ordinator in Syria, told our correspondent that getting started with the evacuation operation was the right thing to do, despite the continuing violence and danger to the teams on the ground.
