The report by India's Aircraft Accident Investigation Bureau (AAIB) about the June 12 crash shortly after takeoff raises fresh questions over the position of the critical engine fuel cutoff switches, while suggesting that Boeing and engine maker GE had no apparent responsibility for the accident.

"We are aware of reports of the death of a U.S. citizen in the West Bank," a State Department spokesperson said, adding the department had no further comment "out of respect for the privacy of the family and loved ones" of the reported victim.
