World News : Iran judge won't sign "hikers" release before Tuesday: lawyer

TEHRAN (World News) - The lawyer for two U.S. men convicted of spying in Iran said on Sunday their release could be delayed until Tuesday as the judge in the case was on vacation.

Iranian President Mahmoud Ahmadinejad told a U.S. television interviewer last week that Shane Bauer, 28, and Josh Fattal, 29, would be freed in coming days in a humanitarian gesture ahead of his trip to the United Nations in New York.

The Gulf State of Oman has sent a plane to Iran to pick up the Americans, a foreign ministry official said on Friday.

The men were arrested on the border with Iraq in 2009 where they said they were hiking. They were found guilty of illegal entry and espionage and were sentenced last month to eight years in prison.

The deal to release them still has to be signed off by Iran's judiciary, which said on Wednesday the release was not imminent, reflecting a rift between the country's ruling hardline elites.

Lawyer Masoud Shafie said he was seeking a signature from the judg e to secure their freedom.

"We have to wait until Tuesday when the judge will be back, so that he can sign the documents," Shafie told World News.

He said last week the men would be released on $ 500,000 bail each. A third American, Sarah Shourd, was arrested with the men but was allowed home on $ 500,000 bail in September 2010.

Shourd's release was similarly delayed for several days by the judiciary after it had been announced.

Washington has denied the three Americans were spies and their supporters complain that no evidence against them has been made public. Their trial took place behind closed doors.

Ahmadinejad's announcement, to U.S. media, that the men would be freed was seen by analysts as a bid to improve his international standing ahead of the U.N. General Assembly meeting which st arts on Wednesday.

Neighbouring Iraq said it has helped to mediate the release.

"I predict that before the visit of Dr. Ahmadinejad to New York, they will be freed," Nazem Dabbagh, the Iraqi envoy to Iran, told World News TV.

"Maybe (the timing of the release) is because Iran wants to show its good will while he is there, and for news to be hot and to be announced as the conference is taking place."

The Iraqi envoy said the detainees were expected to be handed over to the Swiss embassy in Iran, which represents U.S. interests in Tehran.
