Amman: Two managers of a Jordanian website have been arrested for spreading rumours that an Iraqi militant had been freed in exchange for a Japanese hostage, a judicial source said Thursday.

The owner of the Saraya News site, Hashim Al Khalidi, and editor-in-chief Saif Obeidat could face up to 15 years in prison if convicted.

Daesh is demanding the release of Iraqi would-be suicide bomber Sajida Al Rishawi, who is on death row in Jordan, in return for Japanese journalist Kenji Goto.

The kingdom is under heavy pressure at home and from Japan to save a Jordanian pilot held by Daesh militants, Mu’ath Al Kassasbeh, as well as Goto.

On Wednesday Saraya News reported that Al Rishawi had been freed and had arrived in Iraq to be handed over to Daesh in exchange for Goto, which the authorities quickly denied.

“By order of the prosecutor general of the State Security Court, Hashim Al Khalidi and Saif Obeidat were arrested after the publication of rumours of the release of an Iraqi suicide bomber as part of a deal with Daesh,” the source said.

They are accused of “having used means of communication to propagate the ideas of a terrorist organisation and actions that could encourage violence against Jordanians and acts of revenge,” the source added.

Jordan, which is accused by rights groups of restricting freedom of speech and of the press, has ordered the closure of the site.

In a new audio recording released on Thursday, a voice identifying itself as Goto says his captors will kill Kassasbeh if Al Rishawi is not handed over by sunset.

Amman has offered to free the Iraqi woman, who was convicted for her part in triple-hotel bombings in the Jordanian capital in 2005 that killed 60 people, if IS releases their pilot unharmed.

Al Kassasbeh was captured on December 24 after his F-16 jet crashed while on a mission against the jihadists over northern Syria.
