All main parties have announced their opposition to the coup and backing for the Turkish government.

"I certainly believe that coup plotters will not succeed," Erdogan told CNN Turk television, speaking on FaceTime via mobile phone.

"I urge the Turkish people to convene at public squares and airports. I never believed in a power higher than the power of the people."

A presidential source said Erdogan was in a secure location as per government protocol.
