Japan’s prime minister has described the apparent killing of hostage Haruna Yukawa by ISIL militants as “outrageous” and “impermissable.”<br /><br /> Shinzo Abe says a recording and an image <br />of what appears to be the decapitated body of the Japanese captive were likely to be authentic. <br /><br /> “This an outrageous and unacceptable act and it gives me a strong sense of anger. We strongly condemn what has happened,” said Abe.<br /><br /> Abe is calling for a second hostage, Kenji Goto, to be freed.<br /><br /> “We ask for the remaining Japanese citizen, that no harm comes to him – and we ask that he is released as soon as possible.”<br /><br /> In the apparent recording, Goto says the militants would free him in exchange for the release of an Iraqi held in Jordan.<br /><br /> His captors have apparently dropped an earlier ransom demand. <br /><br /> Yukawa was seized in August after going to Syria. Goto, a veteran war correspondent, is said to have travelled to the same country two months later.
