Turkey has dismissed 1,389 personnel from the army for suspected links to Fethullah Gulen, a US-based businessman it blames for a failed coup attempt, the state-run Anadolu Agency reported.

The announcement on Sunday came hours after President Recep Tayyip Erdogan said he planned to introduce several changes to the military, including shutting training academies.

"We are going to introduce a small constitutional package [to parliament] which, if approved, will bring the National Intelligence Organization (MIT) and chief of staff under the control of the presidency," the AFP news agency quoted Erdogan as saying.

Erdogan added that "military schools will be closed ... and a national military university will be founded" as part of a wide-ranging shake-up of the military.

He also said that in future the heads of the land, sea and air forces would have to report directly to the defense minister, Fikri Isik.

The president has blamed intelligence failures for the failed coup and said he was unhappy with information he received from the MIT and its chief Hakan Fidan on the night of the coup, complaining that valuable time had been lost.

Erdogan also said a three-month state of emergency declared in the wake of the coup could be extended.

"If things do not return to normal in the state of emergency then like France we could extend it," Erdogan said, referring to a similar move in France after a string of attacks there.

The president said that until now 18,699 people had been detained since the coup, with 10,137 of them placed under arrest.

Thousands of the detained have now been released, with an Istanbul court freeing 758 soldiers late on Friday, adding to another 3,500 former suspects already freed.
