The Boeing 777, Turkish Airlines Flight 001, encountered the turbulence shortly before it landed at 5:35 p.m., according to the Federal Aviation Administration.
The FAA said in a statement that the pilot declared an emergency and reported that several passengers were injured. Several ambulances arrived at the airport. The Fire Department said in a tweet that the injuries were not life-threatening.
Turkish Airlines did not immediately respond to a request for comment.
Turbulence is the leading cause of injuries to passengers and flight attendants, excluding fatal accidents, according to the FAA.
In 2017, 17 passengers and crew members were injured in turbulence, according to the FAA. In 2016, that number was 44. Since 2002 the highest annual number has been 94, in 2009.
