(BBC) Ethiopian Airlines officials have bluntly rejected the findings of a Lebanese investigation into an air crash off Lebanon in January 2010.
The Lebanese report blames pilot error for the crash of flight ET409, in which 90 people died, sources say.
But Ethiopian Airlines officials say the plane exploded, which they say points to sabotage, a lightning strike or shooting down.
The Lebanese report was due to be released on Tuesday.
The Addis Ababa-bound flight crashed minutes after take-off from Beirut in stormy weather on 25 January 2010, with no survivors.
Lebanese Transport Minister Ghazi Aridi told AFP news agency it was "clear" that "there were errors on the part of the pilot and co-pilot who are entirely responsible for the plane crash".
