Twenty-nine passengers are being treated for injuries sustained during major turbulence on a Turkish Airlines flight en route to John F Kennedy International Airport, authorities say. 

Spokesman Steve Coleman of the Port Authority of New York and New Jersey said that four passengers were taken to a hospital after the plane landed Saturday at 5.35pm. 

One had a broken leg and others suffered bumps, bruises and cuts.

Coleman says most of the passengers were treated inside an airport terminal.

The New York City Fire Department tweeted about the incident on Saturday evening, reporting that all of the wounded, two of whom are children, had sustained non-life-threatening injuries. 

The FDNY initially reported that 32 people were injured but later downgraded the number to 29.

The Turkish Airlines Flight 1 reportedly encountered the turbulence about 45 minutes before landing at JFK.

The Boeing 777 had taken off from Istanbul with 326 passengers and 21 crew members.  

The National Weather Service’s Aviation Weather Center had warned pilots of severe turbulence over New England on Saturday evening.  

The incident comes just hours after neighboring Newark Airport was forced to close all of its runways after a flight from Montreal to Fort Lauderdale made an emergency landing due to smoke in the cargo hold.
