All the groups worldwide that have pledged their allegiance to Isis

The Islamic State of Iraq and the Levant (Isis) is one of the most well funded and ruthless terror groups in history.

While most of the world has been shocked at the wave of brutality the group has unleashed across its territory in Syria and Iraq, the group has pockets of support across the globe who believe in their warped vision of a new-age caliphate.

As well as an estimated 22,000 foreigners who have left their countries of origin to fight on behalf of the group, states such as Qatar and Saudi Arabia have been accused of not doing enough to stem the flow of money to the group from their citizens.

Turkey meanwhile shares a common enemy with Isis in Kurdish fighters.

There is evidence that Bashar al-Assad's Syrian regime helped create Isis by strategically releasing its leaders from prison and continuing to buy oil from the group today.

But aside from individual actors and dodgy dealings by states, there are many self-styled jihadist groups that have pledged support to Isis, which shows the appeal of the Iraq- and Syria-based jihadist group in other regions traditionally dominated by al-Qaeda and local insurgencies.

The fervour with which the group's vision has been embraced shows the power of their propaganda videos and social media outreach.
