Newark Liberty Airport was closed temporarily Saturday morning after an "emergency" situation that shut down departures and arrivals at the airport. 

The New Jersey airport tweeted that as of 9 a.m. local time, an "airport emergency" had stalled all flights and passengers should check with their airlines before beginning their travel. 

This is the second incident in two weeks that has caused the airport to shutter after the tires on a United Airlines jet blew out as it landed at Newark earlier this month. No injuries were reported.

Business Insider could not independently verify the reason for the emergency landing. A call to officials at the Port Authority was not immediately returned.

The Federal Aviation Administration's website said there was a traffic management system underway after an unspecified aircraft incident and that both arrivals and departures would experience delays of 46 and 60 minutes, which are expected to increase. 

A Twitter user who said he was on the flight from New York's LaGuardia Airport to Houston's George Bush Airport, posted that a United Airlines flight had made a safe emergency landing in Newark. 

Passengers on different flights took to social media to describe disruptions in flights at other airports. CBC journalist Jen White tweeted that her departure from Toronto was delayed, pending further information. 

One user appeared to described that the flight he was on was diverted more than 60 miles north to New York's Stewart Aiport, which sits in the state's Hudson Valley, above Manhattan.
