The Islamic State terrorist group on Thursday released an Internet video promising to attack Russia “very soon,” the SITE monitoring group reported on Thursday.
The video was reportedly posted by the Islamic State's foreign media outlet, and told Russians that the group planned to “make their wives concubines and their children slaves.”
The video comes just two weeks after a Russian airliner went down over Egypt's Sinai peninsula in what was Russia's worst ever civilian air disaster.
An Islamic State affiliate later took credit for the disaster, and Russian officials have not ruled out an act of terrorism as the cause.
The Islamic State has previously called for Islamic fighters to take revenge on Russia after President Vladimir Putin launched an air bombardment campaign in Syria against Islamic State militants and opposition forces fighting against Syrian President Bashar Assad.
