India's civil aviation regulator has released a preliminary report indicating that both of the jet's fuel cutoff switches flipped to the "cutoff" position shortly after take-off - but neither pilot believed they had moved the switches manually.

A preliminary report into the deadly crash of an Air India jetliner in June is expected to be released by Friday, three sources with knowledge of the matter said, with one adding the probe had narrowed its focus to the movement of the plane's fuel control switches.
