Out in the open in freezing weather, Mustafa Hamadi and his family settled into their makeshift tent in the village of Killi, in the northwestern Syrian province of Idlib - their second displacement in less than a year. The sub-zero temperatures on the night of February 11 kept them awake so, just before midnight, Mustafa moved the gas heater inside the tent.
By morning, Mustafa, his wife Amoun, their 12-year-old daughter Huda and their granddaughter Hoor, who was just three years old, were all found dead of carbon monoxide poisoning.
