All 327 passengers were taken off the plane and were "served snacks and other beverages," said Dhananjay Kumar, a spokesman for Air India.



The airline initially tweeted that the landing was due to a threat, then deleted the post. The flight had been scheduled to arrive at Newark just after 9 a.m., according to FlightAware data.
