The Syrian army says it’s on the verge of cutting through the surrounded, rebel-held area of east Ghouta near the capital Damascus. According to human rights groups, more than 900 civilians have been killed there in the last 18 days and the Red Cross has held back an aid convoy because of the intense fighting. The UN says 400,000 people are trapped in the towns and villages there and are running out of food and medicine. This report shows the desperate struggles of three families living under the siege.
