Abe, speaking to public broadcaster NHK, said chances were high that a recording and an image of what appeared to be the decapitated body of Japanese captive Harman Yukawa, which emerged late on Saturday, were authentic.

Abe also called for the immediate release of the remaining Japanese captive, reporter Kenji Goto, and said he was putting top priority on saving Goto’s life.

But he reiterated that Japan would not give in to terrorism.

“Such an act of terrorism is outrageous and impermissible, which causes me nothing but strong indignation,” Abe said.
