Authorities have started handing over remains of the victims of one of India’s worst aviation disasters, days after the Air India flight crashed and killed at least 270 people, officials said Sunday.

Three days after the crash, only 35 bodies had been handed over to relatives from an overall official death toll of 270.

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.
