TOKYO (AP) — Japanese Prime Minister Shinzo Abe expressed outrage Sunday over a video purportedly from the Islamic State group that shows a militant beheading hostage Kenji Goto.

"I feel indignation over this immoral and heinous act of terrorism," Abe told reporters after convening an emergency Cabinet meeting. He vowed that Japan will not give in to terrorism and will continue to provide humanitarian aid to countries fighting the Islamic State extremists.

The government said it was rushing to confirm the authenticity of the online video.
