An American Airlines flight from New York to New Delhi, India, landed safely in Rome on Sunday afternoon after it was diverted due to a security concern, which later proved to be “non-credible,” the airline said.

Authorities said they received an emailed bomb threat concerning the flight; the threat was later determined to be unfounded.

An American Airlines flight traveling to Delhi made a sudden diversion midair and was escorted to Rome by fighter jets due to a security issue on board.
