The Federal Aviation Administration says a pilot reported visual impairment after a laser struck an airliner landing at Los Angeles International Airport.
FAA spokesman Ian Gregor says the laser strike occurred early Wednesday as US Airways Flight 674 was just east of Santa Monica at 9,000 feet.
The Airbus A321 was arriving from Phoenix.
The FBI says it is investigating the incident. No suspect has been identified.
The FBI recently began offering rewards of $10,000 for information leading to the arrest of anyone who threatens aircraft in a laser attack.
In 2013 the FAA reported nearly 4,000 laser strikes.
In March, a 26-year-old man was sentenced to 14 years in prison after being convicted of shining a laser pointer at a Fresno police helicopter and a hospital helicopter.
