The emergence of more details about the recent tanker attack by Houthi rebels off Yemen still leaves "a considerable degree of ambiguity", according to security sources.
Initial reports suggested a Saudi Arabian aframax, Red Sea Marine Services' 107,000-dwt aframax Gladiolus (built 1998), had been approached by pirate skiffs in the Gulf of Aden on 4 March 172 km south of Nishtun.
