There have already been several massacres in Syria this year, but the latest mass killing appears to be on a whole new scale. This time it's in the Damascus suburb of Daraya – a mostly poor and largely Sunni area, with a population of about 150,000.
Opposition activists say government forces murdered at least 320 people, many shot in the head, execution style. Most of the victims appeared to be men; but women and children were also targeted.
CNN has obtained an extraordinary account of life in the Damascus suburb of Daraya over the last two weeks, just before the neighborhood was overrun by Syrian government troops. The Syrian government has said it targeted Daraya to cleanse terrorist cells from the town but this report shows the townspeople had only just begun to rebuild their lives after the last Syrian Army offensive nearly two months ago. Some of the images in this report are graphic and not appropriate for all viewers. For safety reasons, we are not naming the journalist. You can watch her report in the video above.
