Authorities have so far identified 31 victims of the Air India plane crash in Ahmedabad through DNA testing and 12 families have claimed the mortal remains so far, an official said on Sunday.

The process of DNA matching of former Gujarat chief minister Vijay Rupani was also underway, Dr Rajnish Patel, professor of surgery at the government-run B J Medical College here said.

As many as 230 teams were formed to coordinate with the victims' families, officials earlier said.

The victims included 241 of the 242 passengers and crew members on board the London-bound flight. Former CM Rupani was among the passengers killed in the tragedy.

One passenger miraculously survived.

All but one of the 242 passengers and crew on board the Boeing 787-8(AI171) and another 29 persons, including five MBBS students, on the ground were killed in the plane crash on Thursday.

The aircraft came down moments after taking off from the Sardar Vallabhbhai Patel International Airport before falling inside the nearby campus of the Medical College in Meghaninagar area and going up in flames.
