ISIS publishes annual report detailing its reign of terror across the Middle East

The Isis report uses computer-generated graphics to detail the group's reign of terror in the Middle East. This chart shows the number of explosive devices the group detonated in 2012 and 2013

Another set of graphics in the report shows the weaponry Isis now has in its possession

In 2013 alone, the Islamic State of Iraq and the Levant, or ISIS, says it has carried out nearly 10,000 operations in Iraq, 1,000 assassinations, planted 4,000 improvised explosion devices and freed hundreds of radical prisoners

Isis also claims to have turned hundreds of 'apostates' and says it now has at least 15,000 fighters in its ranks

Out of the 15,000 fighters Isis has at its disposal, 12,000 of them are believed to be from outside Iraq and Syria - the majority of these from neighbouring Middle Eastern countries.

However an estimated 2,000 are believed to have arrived from European countries, including Britain, with a growing number of arrivals from countries such as Malaysia and Indonesia.

Details of the report emerged as new information about the way Isis is funded and attracts recruits came to light, with reports suggesting widespread support in South East Asia, particularly Indonesia - the country with the world’s biggest Muslim population
