NEWARK -- United Airlines cancelled a flight out of Newark Liberty International Airport on Tuesday night after fuel gushed from one of the plane's wings as it taxied to the runway.

A video shot by a passenger shows fuel spilling onto the runway from the edge of the left wing.

Flight 170 was scheduled to depart for Venice, Italy at 6:55 p.m, but was forced to return to the gate.

Passengers were put in a hotel and United will attempt to re-book them on a flight Wednesday, United said in a statement. United described the incident as a "fuel leak," but didn't mention where the leak originated.
