A leaked dossier of Islamic State terror group published today in a leading newspaper show the sophisticated plans of the militant group in building a state in Iraq and Syria complete with government departments, a treasury and an economic programme for self-sufficiency.

The 24-page dossier outlines how the terror group is trying to build a state complete with guidelines for education, natural resources, industry, diplomacy, propaganda and the military.

The 10 chapter-long document, titled 'Principles in the administration of the Islamic State', dated sometime between July and October 2014, was obtained by the Guardian newspaper.

It is written by an Egyptian called Abu Abdullah al-Masri and gives an insight into the well-funded regime and outlines how fighters must receive 'training on bearing light arms'.

Charlie Winter, a senior researcher for Georgia State University told the newspaper: 'Far from being an army of irrational, bloodthirsty fanatics, IS is a deeply calculating political organisation with an extremely complex, well-planned infrastructure behind it.'

Abdullah also calls for a single identity for the terror group to unite both foreigners and locals and makes the case for establishing independent 'factories for local military and food production' in the dossier.
