Earlier, a three-minute video appeared on the Internet showing one of the Japanese hostages held by Islamic State Kenji Goto with a picture of the beheaded body of his fellow captive, Haruna. The hostage claims on camera his partner was executed and says the jihadists want him swapped for a female suicide bomber, Sajida al-Rishawi, an alleged attempted suicide bomber, who is believed to be connected to the attack on a hotel in Jordan in 2005. The Japanese government could not fully confirm the authenticity of the video. However, Prime Minister Shinzo Abe said that the ongoing investigation has showed that it appears to be credible.
