The Islamic State in Iraq and the Levant ISIL, one of the most brutal and dangerous terrorist groups in modern times which has captured territory in Iraq and Syria has declared itself an Islamic “caliphate” and called on Islamic factions worldwide to pledge their allegiance. The move is an expansion of the group’s ambitions to wage a war and pose a direct challenge to the central leadership of Al Qaeda, which has already disowned it. In a statement from the group posted on Islamist websites and Twitter, the group has renamed itself “Islamic State” and proclaimed its leader Abu Bakr al-Baghdadi as “caliph”, the head of the state. But the grope is not only a threat to the region, it poses a threat to UK national security with hundreds of British Muslims fighting there and will sure come home to cause atrocities here.
