The Indian naval vessel INS Tabar sank a suspected pirate "mother ship" in the Gulf of Aden and chased two attack boats into the night, officials said Wednesday, yet more violence in the lawless seas where brigands are becoming bolder and more violent. The Indian navy said the pirates fired on the INS Tabar after the officers asked it to stop to be searched. (AP Photo/Rajesh Nirgude, File)
