United Airlines flight 2160 from San Francisco made an emergency landing at Newark-Liberty International Airport early Tuesday morning.

Multiple emergency vehicles surrounded the plane at 2:35 a.m. after the tower notified the crew that smoke was coming from one of the engines, according to United.

"Customers exited the aircraft on the taxiway and were bused to the terminal safely. Maintenance is inspecting the aircraft."

Twitter user Seema Amble wrote that smoke was coming out of the right engine and that there was fuel leaking, but passengers were not told to evacuate.

Twitter user @Amanda_Pawluk told FOX 5 NY that passengers were alerted to a fire in the engine and that fuel was leaking.

"They never called it an emergency landing though."

Port Authority police said a hydraulic fuel leak is suspected as a potential cause for the smoke.

A few hours later, Port Authority police say they responded to an incoming Delta flight experiencing possible engine failure.

The plane was towed to a terminal and inspected for an engine fire.

No injuries were reported in either incident.
