The brutal treatment of senior military officials by Gülenist Terror Group (FETÖ)-affiliated putschists at the Turkish General Staff Headquarters on the night of July 15 has been revealed by exclusive footage obtained by A Haber News Channel.

The footage shows that the coup plotters entered the headquarters at 9:22 p.m. local time, after realizing that their plans to take over were discovered by state officials.

The indictment says the coup, which killed 248 people, was originally planned to start at 3 a.m. according to FETÖ members, but a general at the army headquarters told fellow coup plotters to reschedule it when he heard that FETÖ infiltrators in the army would be arrested that night.

According to the footage, putschists wait in ambush for Land Forces Commander Gen. Salih Zeki Çolak to arrive at the General Staff Headquarters and swoop down on him as soon as he's there. They immediately killed Gen. Çolak's Sergeant as he was trying to protect Çolak, and shot the guard commissioner who also resisted.
