Indian authorities have started handing over remains of the victims of one of India's worst aviation disasters after identifying some through DNA tests.

Officials from the US National Transportation Safety Board (NTSB) surveyed the site of Air India plane crash that killed at least 271 people, sources said on Sunday, with families continuing to wait for DNA profiling results to identify charred bodies.

India’s government is urgently inspecting all Boeing 787s after a devastating Air India crash that claimed at least 270 lives this week, the aviation minister said on Saturday, adding that the authorities were investigating all possible causes.
