At least 2,839 military personnel were detained across Turkey on Saturday after a coup attempt, according to the Interior Ministry.

The ministry also suspended several parallel state military personnel including five generals and 29 colonels. The attempted coup left 265 people dead.

President Recep Tayyip Erdogan had earlier announced that a group within the Turkish military attempted an overthrow of the government.

In the moments after the attempted coup was launched Friday night, Erdogan urged Turks in a televised message to “go to squares, let us give them the best answer.”

Arriving in Istanbul hours later, the president said he would not leave Ataturk Airport until the situation in the country returns to normal.

“Turkish Airlines began its operations. There is a small distress in Ankara,” Erdogan told a large crowd gathered at the airport.

“There is no leaving here until this situation goes back to normal. I will not leave, too,” he said.

Erdogan slammed United States-based preacher Fetullah Gulen, who is accused of leading a terrorist organisation and attempting to infiltrate and overthrow the democratically-elected government.

“It is enough the betrayal you have done to this nation,” Erdogan said, without mentioning Gulen’s name, and calling on him to return to Turkey to face trial.

At least 90 people were martyred and more than 1,000 others injured during the coup attempt.

Meanwhile, Turkey’s top judicial board has suspended 2,745 judges, including 541 court of first instance judges and 2,204 judicial court judges, over Friday’s attempted coup.

The Supreme Board of Judges and Prosecutors (HSYK) also decided to terminate the membership of five of its members after the Ankara Chief Public Prosecutor's Office’s decision to detain them. Four have been remanded into custody.

Forty-eight members of the Council of State linked to the FETO/PDY terrorist organization were also remanded into custody, and out of 140 Court of Appeal members detained who were linked to the FETO/PDY, 11 were remanded Saturday.

Friday night saw military elements make a “vile” attempt to overthrow Turkey’s elected government, according to Prime Minister Binali Yildirim. Around 160 people were martyred in the ensuing violence.

Some 2,839 military personnel involved in the coup attempt have been arrested, and 20 pro-coup soldiers, including some senior officers, were killed in Friday night’s attempt to overthrow the government.
