More than 2,000 people were killed when an earthquake struck central Turkey and north-west Syria, in one of the most powerful quakes in the region in at least a century, while a second powerful tremor hours later threatened to overwhelm rescue efforts.

Thousands more were injured as the quake wiped out entire sections of major cities in a region filled with millions of people who have fled the civil war in Syria.
