MOMBASA, Kenya – Undeterred by U.S. and French hostage rescues that killed seven bandits, Somali pirates brazenly hijacked three more ships in the Gulf of Aden, the key waterway that’s become the focal point of the world’s fight against piracy.

The latest trophy for the pirates was the M.V. Irene E.M., a Greek-managed bulk carrier sailing from the Middle East to South Asia, said Noel Choong, who heads the International Maritime Bureau’s piracy reporting center in Kuala Lumpur.
