An Italian jet from Milan had to be evacuated shortly after arriving at JFK Airport on Sunday because officials received a bomb threat against the plane.

Passengers were taken off the aircraft and forced to wait for hours on buses parked on the tarmac after Alitalia Flt. 604 landed around 4:10 p.m.

Port Authority cops searched the plane with bomb-sniffing dogs but found no threat. The incident is still under investigation.
