All passengers had to be immediately evacuated.

The Delhi-Zurich flight was abandoned at around 01:08 a.m. local time. There were 232 people on board, and the injured passengers were later admitted to a local private hospital.

A full emergency was declared at Delhi Airport, said the airport's management in an official statement.
