Taken from the current Yemen thread and cited in part:
The biggest beneficiary of the war has been AQAP, which now controls some six hundred kilometers of the southern coastline—from just outside Aden to Mukalla, the fifth largest city in Yemen and the capital of Hadramaut province. When AQAP seized the Mukalla at the start of the war, they looted $100 million from its banks. They are now earning at least $2 million and perhaps as much as $5 million a day in smuggling oil. The group is stronger today than ever before.

My interest was prompted by a "lurker" asking does the anti-money laundering legal structure work, when terrorist groups can be self-financing?
