NEW DELHI: Indian authorities were combing the site of one of India’s deadliest aviation disasters on Friday, after an Air India plane crashed in the western city of Ahmedabad less than a minute after takeoff, killing all but one of its passengers.

The London-bound Boeing 787-8 Dreamliner, which had 242 people on board, killed dozens more people when it crashed into a medical college hostel just outside Ahmedabad airport and burst into flames on Thursday afternoon.

The sole survivor, a British citizen of Indian origin, is being treated in hospital, the airline confirmed.

“We are all devastated by the air tragedy in Ahmedabad. The loss of so many lives in such a sudden and heartbreaking manner is beyond words. Condolences to all the bereaved families,” Indian Prime Minister Narendra Modi wrote on social media after visiting the crash site in the capital of his home state of Gujarat.

The passengers comprised 169 Indian citizens, 53 Britons, 7 Portuguese and a Canadian.
