Syrian refugees who fled their homes in Damascus shortly before the chemical weapons attack told ITV News that the world must act now to prevent further atrocities.
Sapha, who is just one of 140,000 Syrian refugees at the Zaatari camp in Jordan, was forced to flee the war-torn country without three of her children.
She told our Correspondent Martin Geissler: "It's awful. My body is here but my heart is at home. I don't know where my children are. I don't know what's happened to them. It's tearing out my heart."
