An online video was released Saturday night which claims to show the beheading of Japanese journalist Kenji Goto, 47, by an Islamic State militant. If true, the murder ends days of negotiations by diplomats trying to save hit life. The video was released on militant websites and showed the symbol of the al-Furqan media arm of the Islamic State.

The video, which has not been authenticated by Japan, comes two days after the expiration of a deadline set by the Islamic State extremists for the government of Jordan to give in to their demands by exchanging a would-be suicide bomber for Goto’s life. Jordan had agreed to release the female suicide bomber, Sajida al-Rishawi, only if the extremists produced proof that Jordanian pilot First Lt. Moaz al-Kasasbeh was still alive. al-Kasasbeh was shot down on Dec. 24 over Syria during airstrikes against the Islamic State, who threatened to kill him, as well as Goto, if al-Rishawi was not released.

Although not verified, the 67-second-log video is similar to other beheading videos released by the Islamic State. It shows Goto kneeling in an orange jumpsuit. A black-masked extremist with British-accented English, who appears to be the man known as Jihadi John in previous videos, is standing behind him.

The masked man blames Japan’s Prime Minister, Shinzo Abe, for the fate of Goto. He says that because of Japan’s decision to participate in an “unwinnable war,” Goto will be slaughtered and they will carry on and “cause carnage” wherever Japanese people are found. Prime Minister Abe recently promised $200 million in nonlethal aid to countries fighting against the Islamic State.

The militant then says “So let the nightmare for Japan begin,” and begins cutting Goto’s neck. Goto is looking calmly into the camera, closing his eyes at the last minute. The screen goes black, and then a still shot appears showing the body, apparently decapitated, with hands still bound and the severed head placed on his back.

Goto was captured in October, after traveling to Syria to try and obtain freedom for Haruna Yukawa, another Japanese hostage who extremists claim was beheaded a week before. The Islamic State had demanded $200 million to release both men, but after their 72-hour ultimatum expired they said that Yukawa had been killed. The militants’ demand then changed to an exchange of Rishawi for Goto. This proposal was supported widely in Jordan, but officials insisted that they wanted their pilot, al-Kasasbeh, also released. The most recent video makes no mention of al-Kasasbeh.
