Senior government source tells MEE: 'The coup has failed'

“The coup has failed," a senior government source told MEE early on Saturday on the condition of anonymity. 

"We are in control of Istanbul and have liberated all the places occupied by the coup plotter and we are in control of the vast majority of Ankara apart from small isolated areas. It will be over [later this] morning.”

Additionally, a Turkish official told MEE's Suraj Sharma in Istanbul that a Turkish intelligence building was targeted by the coup plotters using hijacked helicopters.

There were no casualities, he said, speaking on the condition of anonymity.
