Air India confirmed the incident on flight AI 130 from London Heathrow to Mumbai but did not specify the cause.

"A few of them were taken to the medical room (at Mumbai's Terminal 2 ) on wheelchairs," an airport official, also on condition of anonymity, added.

The spokesperson said the two passengers and two cabin crew members who were taken to the medical room for further examination were later discharged.P6...
