A Cathay Pacific Boeing 777 bound from Hong Kong to Los Angeles International Airport has diverted to a U.S. air base in the Aleutian Islands.

Federal Aviation Administration spokesman Ian Gregor says Flight 884 declared an emergency and landed early Wednesday morning at Eareckson Air Station in Shemya, Alaska.

Gregor referred questions about the reason for the diversion to the airline. There was no immediate response to an email seeking comment from Cathay Pacific or a phone call to Eareckson.
