The head of UN observers in Syria has urged warring parties to allow the evacuation of women, children, elderly and injured people from conflict zones.
Gen Robert Mood also admitted that "attempts to extract civilians" from the besieged city of Homs over the past week had been unsuccessful.
Homs has reportedly been under heavy bombardment from government forces.
The UK-based Syrian Observatory for Human Rights has said over 1,000 families in Homs need to be evacuated.
The Observatory said at least one person had died in yesterday's violence in Homs and that 10 other deaths had been reported elsewhere in the country.
