ISIS militants have reportedly released a video showing the beheading of Japanese journalist Kenji Goto. Goto is the second hostage to be executed this month after negotiations broke down between ISIS and the Japanese government.

From the Associated Press:

“I feel indignation over this immoral and heinous act of terrorism,” Prime Minister Shinzo Abe told reporters after convening an emergency Cabinet meeting.

“When I think of the grief of his family, I am left speechless,” he said. “The government has been doing its utmost in responding to win his release, and we are filled with deep regret.”

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 White House released a statement in which President Barack Obama also condemned “the heinous murder” and praised Goto’s reporting, saying he “courageously sought to convey the plight of the Syrian people to the outside world.”

Obama applauded Japan’s “steadfast commitment to advancing peace and prosperity in the Middle East and globally, including its generous assistance for innocent people affected by the conflicts in the region.”

According to Cabinet Secretary Yoshihide Suga, Japan will increase its humanitarian aid to the region, but will not offer its Self-Defense forces in the fight against ISIS, or join air raids.

The situation for Goto, and Jordanian fighter pilot and fellow hostage Muath al-Kaseasbeh, spiraled earlier this week as negotiations broke down between Jordan and ISIS rebels. According to the AP, the Muath’s fate is still unknown:

He [Cabinet Secretary Yoshihide Suga] said it would be “inappropriate” to comment on the status of the Jordanian pilot, Muath al-Kaseasbeh. He was captured in December when his F-16 crashed near the de facto capital of the Islamic State group, which controls about a third of both Syria and neighboring Iraq in a self-declared caliphate.

Jordan’s government spokesman, Mohammed al-Momani, also declined comment. Earlier this week, Jordan offered to free an al-Qaida prisoner for the pilot, but demanded and said it never got proof he was still alive.

Militants continue to demand the release of Sajida al-Rishawi, an al-Qaeda operative and attempted suicide bomber currently on death row in Jordan.
