Some of the British families who lost loved ones in the Air India crash in Ahmedabad have been sent the wrong remains, a lawyer says.

The mistakes were found after DNA testing by a coroner in London. The Indian government said bodies of the Flight 171 victims “were handled with utmost professionalism.”

A top-level probe is underway after British families whose loved ones perished in last month’s crash were given “co-mingled” remains.
