Western intelligence officials suspect the ultra-hardline Sunni group of planting a bomb in a Russian passenger plane which crashed in Egypt's Sinai Peninsula on Oct. 31, killing all 224 passengers and crew.

Islamic State militants fighting Egyptian security forces in Sinai said they brought down the plane which was taking Russian tourists back home from the Egyptian tourist resort of Sharm al-Sheikh.

Russia's security agencies will undoubtedly look into a video, 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.
