Governments Give More Help To Iraqi Troops Under Attack

The brutal, extremist group, which claims to have fighters from across the world, has announced the establishment of a "caliphate" - an Islamic state - across parts of Iraq and Syria and forced many minority communities from their homes.

Nearly 13 years on from the devastating 9/11 attacks by al-Qaeda, the group, its affiliates and other jihadist groups are still in business.

Three Western hostages have been beheaded by Islamic State militants recently.

They were among dozens of journalists and aid workers being held hostage in Iraq and Syria.
