A father, his five-year-old daughter and a 10-year-old girl were among those rescued from the rubble of collapsed buildings in southern Turkey, almost a week after the earthquake that flattened the region and neighbouring north-west Syria.

With rescue efforts in their sixth day, the window for finding survivors is shrinking rapidly: experts say the survival rate of people trapped after an earthquake is 74% within 24 hours, but falls to 22% after 72 hours and just 6% by the fifth day.
