A WEBSITE affiliated with Chechen rebels has released a video in which insurgent leader Doku Umarov claims responsibility for last month’s deadly suicide bombing at Russia’s largest airport and threatens more bloodshed if Russia does not leave the region.

Russian authorities today said one of the insurgents killed in a day-long gun and tank fight in Dagestan was a top militant suspected of being the mastermind of one of Russia’s deadliest terrorist attacks.

Chechen warlord Shamil Basayev claimed he managed the militant attacks in the southern Russian city of Nalchik that officials say left at least 139 people dead, according to a statement posted on a Chechen rebel-connected website.
