London officials are sure that an explosion is a reason of the Russian A321 airliner crash. Moreover, it was allegedly orchestrated by the leader of the Islamic State organization Abu Osama al-Masri. British 'Sunday Times' disposes of such an information.
According to the newspaper, the bomb could have been assembled by the Islamic State representatives in the Sinai Peninsula. Great Britain even offers its help to investigate the mysterious tragedy. To conduct it, the country is ready to deploy its forces of Special Air Service in Egypt. However, Moscow and Cairo call not to draw hasty conclusions. And any version now is still just a conjecture.
