Incident: RO/RO evades pirates

A RO/RO vessel in the Gulf of Aden (not otherwise identified) is approached at 0639 hours by armed men in masks in four speedboats. The targeted ship fired two flares at its pursuers and contacted warships for help. While the RO/RO took evasive action, a helicopter arrived 30 minutes later causing the speedboats to return to a mother ship. (ONI Worldwide Threat to Shipping, 5/27/09)
