NEWARK, N.J. - Newark Liberty International Airport was shut down for about an hour Saturday morning due to an airport emergency, according to officials.
The airport's official Twitter account said shortly before 9 a.m. that "due to an airport emergency there are currently no arrivals nor departures from Newark Airport."
United Airlines' official account subsequently informed customers that the Federal Aviation Administration initiated a mandatory ground stop at the airport because of a disabled aircraft on the runway.

Passengers are told to expect delays after the shutdown and are advised to check with their carriers before coming to the airport.
The FAA website said to expect departure delays of up to one hour or more.
A call to officials at the Port Authority was not immediately returned.
Earlier this month, there were delays at the airport after a United Airlines passenger jet skidded off the runway.
