Tanks and soldiers have been seen on the streets of Istanbul and Ankara.
A solider in Istanbul has been filmed saying “it’s a coup, go home.”
Having confirmed his belief that an attempted coup was underway, Binali Yıldırım said: “We are focusing on the possibility of an attempt [coup]. There was an illegal act by a group within the military that was acting out of the chain of military command. Our people should know that we will not allow any activity that would harm democracy.”
The Dogan news agency said one-way traffic on the Bosporus and Fatih Sultan Mehmet bridges were blocked. Video footage showed the bridge being blocked by military vehicles.
