In this photo released by Indian Navy PRO, anti-piracy operations by Indian Navy's warship INS Tabar in the Gulf of Aden Tuesday, Nov. 18, 2008. An anti-piracy watchdog group on Thursday welcomed an Indian warship's destruction of a suspected pirate vessel in waters off Somalia, where hijackings have become increasingly violent and the hijackers increasingly bold. In a rare victory in the sea war against the Somali pirates, the Indian navy's INS Tabar sank a suspected pirate 'mother ship' in the Gulf of Aden and chased two attack boats on Tuesday.
