TOKYO—The father of the Japanese hostage purportedly shown in a video as having been killed by Islamic State militants is hoping against hope his son could still be alive.
“My mind went totally blank,” Shoichi Yukawa told reporters Sunday, a day after news broke of the video footage. “I am hoping deep in my heart that it is not true.”
Haruna Yukawa, a 42-year-old adventurer, was taken hostage in Syria last year.
