(CNN)As the sun set Thursday in the Middle East, did two ISIS captives -- one a Jordanian pilot, the other a Japanese journalist -- fall with it? That was the question following a new message, purportedly from the terrorist group, that pushed Jordan to bring convicted terrorist Sajida al-Rishawi to the Turkish border by 5:30 p.m. (9:30 a.m. ET). If they didn't, according to the message, Jordanian pilot Moaz al-Kassasbeh would be killed, followed soon thereafter by Kenji Goto of Japan. For days, Jordanian officials have said they're willing to swap al-Rishawi for al-Kassasbeh. Government spokesman Mohammed al-Momani reiterated as much late Thursday afternoon, about an hour before the purported deadline. He said Jordan is not about to pull off a deal yet, having received no proof that its pilot is still alive.
