IQALUIT, Nunavut -- Swiss International Air Lines says a flight bound for Los Angeles diverted to Nunavut on Wednesday.

The airline says the plane landed safely in Iqaluit after being diverted due to a "technical irregularity."

It says a malfunction message led to an automatic shutdown of the left engine, adding that is what the system was programmed to do.

The flight from Zurich is expected to arrive about four hours late in Los Angeles.

The plane is a Boeing 777-300ER which can carry more than 300 passengers.
