A United Airlines passenger jet skidded off a runway at Newark Liberty International Airport on Saturday, shutting down service for the New Jersey transportation hub, officials said.

There was no immediate word of any injuries.

Port Authority Police Department cops and Emergency Service Unit teams were sent to the airport following reports that the plane had veered off the runway at about 1:30 p.m. Port Authority did not immediately respond to a request for comment.

The airport was immediately shut down. “Due to an airport emergency there are currently no arrivals nor departures from Newark Airport,” Newark Liberty tweeted. “Please check with your carrier before coming to the airport.”
