In Somalia's main pirate lair of Haradheere, the sea gangs have set up a cooperative to fund their hijackings offshore, a sort of stock exchange meets criminal syndicate.

Heavily armed pirates from the lawless Horn of Africa nation have terrorized shipping lanes in the Indian Ocean and strategic Gulf of Aden, which links Europe to Asia through the Red Sea.

The gangs have made tens of millions of dollars from ransoms and a deployment by foreign navies in the area has only appeared to drive the attackers to hunt further from shore.

It is a lucrative business that has drawn financiers from the Somali diaspora and other nations -- and now the gangs in Haradheere have set up an exchange to manage their investments.
