Cracks in the international alliance against terrorism, particularly countries' inability to even agree on what constitutes terrorism and who is a terrorist, are compromising efforts to combat it.

The horrific terrorist attack on Istanbul's Ataturk Airport, which left 44 people dead and almost 240 injured, has tragically highlighted this once again.

The three suicide attackers have reportedly been identified as being Russian, Uzbek and Kyrgyz nationals, and Ahmed Chataev, a Russian citizen of Chechen origin, has been identified as the mastermind behind the atrocity.
