The remains of the Air India crash victims are handed over to their families.

AHMEDABAD, India (AP) — Authorities have begun releasing the remains of victims of one of India's worst aviation disasters, days after the Air India flight crashed, killing at least 270 people, officials said Sunday.

The London-bound Boeing 787 crashed into a medical college dormitory in a residential area of ​​the northwestern city of Ahmedabad minutes after takeoff on Thursday, killing 241 people on board and at least 29 on the ground. One passenger survived.

Hundreds of relatives of the crash victims provided DNA samples at the hospital. Most of the bodies were charred or mutilated, rendering them unrecognizable.

Rajneesh Patel, an official at the Ahmedabad Civil Hospital, said authorities have so far identified 32 victims through DNA mapping and that their families have been informed. He added that the remains of 14 victims have been handed over to their families.

The families of the victims waited outside the hospital morgue while authorities completed the formalities and transferred the bodies in coffins to ambulances.

Most expressed frustration with the slowness of the identification process. Authorities say it typically takes up to 72 hours to complete the DNA comparison and that they are speeding up the process.
