'Avoid guessing' over plane crash cause: Sissi

Cairo: Egyptian President Abdul Fattah Al Sissi on Sunday cautioned against making hasty conclusions over a deadly crash of a Russian passenger plane in Sinai.

"In such cases, things should be left for specialists and avoid guessing about  causes of the plane fall," he told an army ceremony in Cairo.

On Saturday, the Airbus A321 plunged to the ground shortly after taking off from the Red Sea resort town of Sharm Al Shaikh, killing all 224 people on board. The aircraft was en route to the Russian city of St Petersburg.

The cause of the crash is not known yet.

"Such incidents are subjected to massive investigations and complicated technical measures," Al Sissi said in his first public remarks about the tragedy.

He said Egypt had no objection to Russia's engagement in investigations.

Egypt's Chief Prosecutor Nabil Sadek ordered the formation of a commission from the Ministry of Civil Aviation to analyse the crashed airliner's data and voice recorders, state media reported. 

Russian experts have been permitted to join the panel to 'ensure validity of the steps taken,' according to the media.

Egyptian officials have suggested the crash was caused by a technical fault. 

Both Egypt and Russia have dismissed a claim by a Sinai group loyal to Daesh that it had brought down the plane in a rugged area of central Sinai.
