Turkey earthquake: BBC reports from Antakya, a city reduced to rubble

The BBC's Middle East correspondent Quentin Sommerville has seen first hand the destruction in Antakya, a city in the south of Turkey. He described the situation on the ground surrounded by fallen buildings and the sound of sirens.

The death toll has continued to surge after a 7.8 magnitude quake struck near Gaziantep in the early hours of Monday, followed by a 7.5 magnitude tremor.
