From Washington, this is VOA News. I'm Ray Kouguell reporting. Fate of Jordanian pilot held by Islamic State still unknown. Jordan's King Abdullah II says his country is doing everything it can to rescue the captured Jordanian fighter pilot being held by the Islamic State. Amman renewed its pledge to release an Iraqi insurgent on death row in Jordan, Sajida al-Rishawi, if given proof that the pilot is still alive. The new effort came in the aftermath of the jihadists' beheading of a Japanese journalist. ___________________________________________________. President Barack Obama described the killing as "heinous murder." 以下是美国之声发自华盛顿的报道. 我是Ray Kouguell. 被伊斯兰国拘押的约旦飞行员至今生死未卜. 约旦国王阿卜杜拉二世称约旦正尽一切可能解决被伊斯兰国扣押的约旦籍战斗机飞行员.约旦重申如果有证据证明这名飞行员还活着,将用其关押的被判死刑的伊拉克籍叛乱份子Sajida al-Rishawi来进行交换.这是在圣战份子斩首被俘日本记者之后约旦官方做出的营救努力.________________________________________________,美国总统奥巴马也称该行为是十恶不赦的罪行.
