Tokyo: World leaders reacted with outrage today after Islamic State militants announced they had beheaded a second Japanese hostage, as Jordan vowed to do all it could to save a captured airman.

IS claimed in a video released online that it had killed 47-year-old journalist Kenji Goto, the second purported beheading of a Japanese hostage in a week but made no mention of the Jordanian pilot it had also threatened to kill. Japanese Prime Minster Shinzo Abe condemned the "heinous and despicable terrorist acts" and said that "Japan will never yield to terrorism."
