Japan PM Shinzo Abe in Islamic State 'hostages' vow - BBC News
A video purportedly from the group shows a militant threatening to kill two hostages unless a ransom is paid.
In the video, which has not been independently verified, the militant also criticises Japan for pledging aid to countries fighting IS.
The apparent IS video shows a masked man holding a knife and threatening two hostages.
Speaking in English, the militant says he will kill the two men unless a $200m ransom is paid within 72 hours.
