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.

The passenger jet - the same type as the aircraft involved in last week's tragedy - was bound for New Delhi but landed back in Hong Kong about an hour after take-off.

The Air India flight, operated by a Boeing 787-8 Dreamliner, left Hong Kong for Delhi on Monday morning before quickly returning to its origin as a precautionary measure
