Worried relatives of a Jordanian fighter pilot asked their Government on Sunday to be more open about negotiations for his release, after a second ISIS group hostage was shown beheaded in a video purportedly from the militants. The fates of the pilot, lt Muath al-Kaseasbeh, and Japanese journalist Kenji Goto, previously had been linked. The video of the beheading made no mention of the pilot, raising fears for his life.
