On Thursday, an Air India plane crashed in the state of Gujarat in northwestern India. 241 of the plane's 242 passengers died. A further 29 people believed to be on the ground are thought to have died.
Dozens of relatives have left DNA samples to Indian authorities working to identify the victims. In about thirty cases, the identity has been established, according to AP.
In several cases, the remains have been returned to relatives.
Family members and relatives of the victims have expressed frustration that the process is taking a long time.
On Sunday, one of the plane's black boxes was found, where recordings from the cockpit are preserved. On Friday, the second of the plane's two so-called black boxes with information about the flight was found.
The cause of the plane crash has not yet been established. In addition to the formal investigation, a specialized group will look into the circumstances surrounding the crash, and work preventatively so that something similar does not happen again.
