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.

With 260 casualties and only one surviving passenger, the Air India 171 crash is one of the deadliest aviation incidents in recent history — and so far it’s proving to be one of the most frustratingly opaque.

The son of a woman killed in the Air India plane crash has told the BBC "other remains" were found in her casket after her body was returned to the UK. Miten Patel, whose father also died in the crash, said the coroner identified the mixed-up remains and left him to worry: "How many others are in there?"
