The Guardian reported that the leaders of ISIS have sent their fighters to the desert and mountains in separate areas of Iraq and Syria.
The goal of the terrorist group is to create chaos in areas of sectarian or ethnic diversity or to destabilize the security of some areas, the newspaper reported.
The new tactic also includes the deployment of fighters in minority areas, the newspaper said, adding that the organization started to rely on self-financing through theft, kidnapping and blackmail. This means that the organization has lost its ability to receive foreign funding and to make money from investments made by selling oil in Iraq and Syria, the Guardian said.
According to some sources of the British newspaper, ISIS smuggled about $400 million abroad from Iraq and Syria and seeks to increase its resources through money laundering.
