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.

An investigation is underway as to what caused an Air India airliner carrying 230 passengers and 12 crew members to crash shortly after takeoff on Thursday.

Air India's deadly plane crash that killed at least 270 people has triggered a wave of speculation about what led to the world's worst aviation disaster in a decade, but authorities are slowly narrowing down areas of investigation.
