Kremlin says looking into ISIS video threatening attacks in Russia

MOSCOW - Russia's security agencies will undoubtedly look into a video released on Thursday by Islamic State that threatens attacks in Russia, Kremlin spokesman Dmitry Peskov said on Thursday.
"I do not know the authenticity of this video, I do not know the authenticity of these sources, but in any case no doubt this will be material for review by our special (security) services," Peskov told journalists on a conference call.
Al-Hayat Media Center, Islamic State's foreign language media division, released a Russian language video with chants of "Soon, very soon, the blood will spill like an ocean".
