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.

A source familiar with the situation said the bomb threat towards Flight AA292, which was traveling from New York to New Delhi, was sent via email.

Two Italian military fighter jets flanked American Airlines Flight 292 as it arrived but the Federal Aviation Administration did not elaborate on what was the security issue aboard the plane.
