(CNN) -- A Lufthansa flight en route to New York diverted to Shannon Airport in Ireland after a 2-year-old girl died on the flight, Irish and airline officials said.

The flight originated in Addis Ababa, Ethiopia, and was bound for John F. Kennedy International Airport in New York, with a stopover in Frankfurt, Germany, the press office for the Irish police force Garda said.

The girl died during the Frankfurt-to-New York leg of the trip, and the plane was redirected to Ireland, landing there about 2:30 p.m., Garda said.

The cause of death is unknown, and a post mortem exam will be conducted Wednesday, Garda said. Police are investigating the circumstances of the toddler's death. E-mail to a friend
