Investigators have yet to determine which authority will handle the download of data from the crashed MetroJet Airbus A321's flight recorders.

The Russian transport ministry says the recorders have undergone initial inspection, adding that they have received only "minor" damage during the accident.

It adds that the decision on downloading and analysis will be resolved "shortly".

Egypt's civil aviation authority has stated that it has the capability to undertake the task. The Russian ministry says that the work will be carried out in the presence of Egyptian, Russian, French, German and Irish representatives.

Russian transport minister Maksim Sokolov says the debris field from the 31 October crash stretches to 20km2.

Images from the scene indicate that the aircraft broke up into several large sections, with the forward fuselage and wings striking the ground separately to the empennage and engines.
