Shock and confusion Sunday overwhelmed the families and acquaintances of the two Japanese men held captive by the Islamic State group as a new video showed a still image of hostage Kenji Goto holding a picture of what appears to the decapitated corpse of fellow captive Haruna Yukawa.

Yukawa's 74-year-old father, Shoichi, told the media Sunday he was still holding out hope that his son is still alive and that he will give him a hug if he ever sees him again.

"My mind went totally blank," he said at his home in the city of Chiba. "I cannot find any other words."
