AMMAN, Jordan (AP) — The family of a Jordanian fighter pilot held by the Islamic State group said Saturday it has received no word on his fate since the militants threatened to kill him earlier this week. The Islamic State group purportedly threatened to kill Lt. Muath al-Kaseasbeh by Thursday unless Jordan released a female al-Qaida prisoner, Sajida al-Rishawi, from death row. Japan's deputy foreign minister, Yasuhide Nakayama, said late Friday that efforts to free Goto are "in a state of deadlock." The militants later demanded the release of al-Rishawi, 44, who faces death by hanging for her role in a 2005 al-Qaida attack on hotels in Amman that killed 60 people.
