A visibly upset Japanese Prime Minister Shinzo Abe on Sunday vowed to "never forgive terrorists" after the Islamic State group released a video purportedly showing the beheading of hostage Kenji Goto.
"I am extremely angry about these heinous and despicable terrorist acts. We will never forgive terrorists," Abe told reporters in Tokyo.
"We will cooperate with the international community to make them atone for their crimes."
