Military fighter jets were deployed to accompany a Turkish Airlines aircraft following concerns raised by the pilot regarding a potential threat onboard. The flight, TK1853, departed from Istanbul and landed at Barcelona-El Prat Airport with 148 passengers and seven crew members. Reports suggested the presence of a suspicious item on board the Airbus A321, prompting military escort over the Mediterranean Sea in Italian airspace. Spanish and French armed forces participated in the escort, guiding the plane to a safe landing in Barcelona. Law enforcement personnel boarded the aircraft upon arrival while emergency services mobilized. No explosives have been found during luggage checks, and normal airport operations remain unaffected. Authorities believe the situation may have been a false alarm, with passengers relocated to a designated area as efforts are made to inform their families.
