The news this week has been dominated by new revelations into the fate of flight A321 which crashed 23 minutes after taking off from the Sharm al-Sheikh tourist resort eight days ago, killing all 224 passengers and crew. Da'esh (IS) militants fighting Egyptian security forces in Sinai claimed to have brought it down - initially these claims were disregarded but new UK and US intelligence, coupled with analysis of the wreckage, has led investigators to state that they are "90 percent sure" the cause of the crash was indeed a bomb.

In today's events driven society, will the downing of flight A321 prompt Russia to escalate its interventions in Syria? Are the US and UK guilty of a 'shocking failure' to share intelligence?
