It looks like a large group of Ex-KGB rebels are trying to make a political statement in Russia.  Golovko has given us Intel on the group.  Their leader Alexey Grushnev, who is not suspected to be on board the airliner, is believed to be the mastermind behind this terrorist operation.  

Grushnev is a former KGB member who was highly decorated during his many years of service.  With the tremendous cutback by the Russian government after the Cold War, he was RIF'ed by the KGB in an effort to reduce their overall size.  He is suspected of having been behind some terrorist activity over the last few years, but has not been apprehended.
