ISTANBUL, Turkey — Turkish authorities say an operation outside the Aegean resort town of Marmaris has resulted in the capture of nine people suspected of being part of a group that raided a hotel at which President Recep Tayyip Erdogan had been staying during the July 15 attempted coup.

A government official, speaking on condition of anonymity in line with regulations, said three suspects were still on the run at press time (Monday in Turkey).

The president had been on vacation in Marmaris when the coup attempt occurred. A group of soldiers that raided his hotel is believed to have missed the president by an hour or less.

Erdogan issued a new presidential decree yesterday that introduced sweeping changes to Turkey’s military in the wake of a July 15 failed coup, bringing the armed forces further under civilian authority.

The decree, the third issued under a three-month state of emergency declared after the attempted coup, gives the president and prime minister the authority to issue direct orders to the commanders of the army, air force and navy.

It also announces the discharge of 1,389 military personnel, including Erdogan’s chief military adviser, who had been arrested days after the attempted coup, the chief of general staff’s charge d’affaires and the defence minister’s chief secretary.

The changes are part of a broad crackdown in the aftermath of the abortive putsch, which Erdogan blames on US-based cleric Fethullah Gulen who he says was behind the coup. Gulen, who lives in self-imposed exile in Pennsylvania, denies any knowledge of the attempt to overthrow the government.

Authorities have continued to search for army personnel suspected of participation in the failed coup.

Apart from apprehending those who directly participated in the putsch, the government has sought to crack down on those suspected of being members of Gulen’s movement and has been bringing the military under increasing civilian control.

Yesterday’s presidential decree puts the military commands directly under the defence ministry, puts all military hospitals under the authority of the health ministry, and also expands the Supreme Military Council — the body that makes decisions on military affairs and appointments — to include Turkey’s deputy prime ministers and its justice, foreign and interior ministers.

It also shuts down all military schools, academies and non-commissioned officer training institutes and establishes a new national defence university to train officers.

More than 10,000 people have been arrested in the crackdown, most of whom are military personnel. Thousands more have been detained and nearly 70,000 people have been suspended or dismissed from their jobs in the education, media, health care, military and judicial sectors. On Sunday, Turkey’s soccer federation said every member of its committees had tendered their resignations “for the well-being of the ongoing security investigation”.

The Government’s crackdown has caused concern among the country’s Western allies, who have urged restraint. Turkey has demanded the speedy extradition of Gulen from the United States, but Washington has asked for evidence he was involved in the attempted coup and says the US extradition process must be allowed to take its course.

Turkey’s relations with Germany are also coming under strain, with Ankara demanding its crackdown on the Gulen movement extended to Gulen-affiliated schools in Germany, and seeking the extradition of members of the judiciary believed to have ties to the movement who are in Germany.

Germany has a sizeable population of people with Turkish roots.
