A Turkish Airlines (THY) plane flying from Istanbul to Portugal returned to Istanbul Atatürk Airport on April 1 after a bomb threat, the Hurriyet Daily News reports.
Security measures were taken near the plane.
On March 30, another THY plane traveling from Istanbul to Sao Paolo made an emergency landing in Casablanca.
A search of the Boeing 777-300ER plane bound for Sao Paulo discovered the threat was a hoax, allowing the plane to subsequently continue on its route, the company added.
