A whistleblower from the Gülenist Terror Group (FETÖ) said they were aware of Daish's Oct.10 Ankara attack that left 102 people dead, after receiving an email from the encrypted instant messaging app ByLock that warned, "Not to go outside on that day."
According to Sabah daily, a woman said an info message was sent to groups' members via Bylock. "A day before the Ankara attack, we received a message that says 'Tomorrow, there will be a terror attack. Do not go outside. Warn your friends and relatives too.' And I let my friends know and relatives about the situation. A day after this, I learned of the terror attack on the television. I was devastated after learning that dozens of people were dead," said the woman.
On Oct. 10, two suicide bombers linked to Daish blew themselves up at a peace rally. Over 400 people were injured and 102 people were killed in the attack, the deadliest in the history of the Republic of Turkey.
