The US-led coalition against the "Islamic State" (ISIS) terrorist organization is squeezing the group's revenues from oil, taxation and financial markets but it needs to step up its campaign of "economic warfare", a leading British official said Tuesday, according to AFP.
Air Vice-Marshal Edward Stringer, who is leading British government efforts to disrupt ISIS financing alongside international allies, said the jihadist group was showing signs of the pressure on its finances. But the military chief told parliament's foreign affairs committee: "It's a pseudo-state and we need to think in terms of how you take a state structure apart. So we're involved in economic warfare."
