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.

Officials say at least 270 bodies have been recovered, while the lone surviving passenger is still under observation for some of his injuries.

Following the crash, the Directorate General of Civil Aviation (DGCA) instructed the airline to conduct detailed inspections of its Dreamliner fleet.
