After a proposed prisoner swap failed to materialize this week, ISIS released a gruesome video on Saturday purporting to show the beheading of captured Japanese journalist Kenji Goto.

On Saturday morning, ISIS militants released a new video which purportedly shows the decapitated body of "security contractor" Haruna Yukawa, one of two kidnapped Japanese nationals the Islamic State demanded a $200 million ransom for earlier this week.

Two Japanese hostages were unveiled by ISIS this morning in a video demanding a $200 million ransom: A journalist named Kenji Goto, and "security contractor" named Haruna Yukawa. But Yukawa is less a private mercenary than a war tourist—one who traveled to Syria in the wake of a serious mental breakdown.
