CRI听力:Jordan Demands Proof Pilot Alive as IS Deadline Passes

Jordan has been demanding proof that a pilot threatened with execution by the Islamic State group is alive, as a deadline set by the extremists for a prisoner swap expired.

The militant group had threatened to kill airman Muath al-Kasaesbeh unless Iraqi jihadist Sajida al-Rishawi was freed in return for a Japanese hostage.

It's not clear from the group's latest message if they are ready to free al-Kasaesbeh as part of the exchange.

Jordanian government spokesman Mohammad al-Momani says they are still waiting for evidence that the airman is alive and well.

"At this point we would like to emphasize that Jordan requested proof of life for the life of the Jordanian pilot and we have not received that yet. We are in constant contact and coordination with our Japanese friends in order to co-ordinate the effort to secure the Japanese hostage as well."

Jordan has said its priority is to see the airman return home safely.

But it is under heavy pressure at home and from Japan -- a major aid donor -- to save both Kasaesbeh as well as the Japanese hostage Kenji Goto.

There were reports suggesting Jordan is considering freeing another jailed jihadist, along with al-Rishawi, to get the two hostages home.

The extremist group had set a deadline of sunset Thursday for the exchange, but there was no news of the hostages after night fell.
