Newark's Liberty International Airport, one of the nation's busiest, was closed Monday evening after a plane with hydraulic problems made an emergency landing there, according to a report.

There are no reports of injuries in the incident, which occurred Monday evening at just after 7 p.m. Eastern Time, fire department officials told The Star-Ledger.

Capt. John Brown told the newspaper that Newark fire department officials were sent to the scene of the emergency landing at the airport but there was no smoke or fire conditions on board the plane. Brown said the plane may have had a landing gear malfunction.

NBC News New York is reporting that a spokesman for the Port Authority of New York and New Jersey, which runs the airport, said that a Shuttle America flight from Atlanta to Newark landed at 6:40 p.m. and announced a problem with its nose gear before landing.

Authorities said the plane's nose gear collapsed, according to NBC News New York.

Passengers from the plane, which landed near but apparently not at its scheduled destination, were being bused to the Newark terminal and the airport was closed at 6:54 p.m.

There were unconfirmed reports that passengers had to exit the plan via emergency chutes, The Star-Ledger reported.
