The three Americans are reportedly being held in the Evin prison Iran is to free on Saturday one of three detained American hikers accused of espionage, reports say.
They say that Iran’s culture ministry informed reporters about the planned release in a text message.
Shane Bauer, 27, Sarah Shourd, 31, and Josh Fattal, 27 were seized last July after entering Iran from Iraq.
Tehran accuses the Americans of entering Iran illegally and having links to US intelligence.
On Thursday, reporters were told by the text message from the Iranian ministry to come to a hotel on Saturday to witness the release – the same hotel where the parents of the Americans were allowed to meet them recently, the Associated Press news agency reports.
It was not immediately known which of the three hikers would be released.
The hikers’ mothers were allowed to meet their children in Tehran in May.
They insists their children were hiking in northern Iraq’s Kurdistan region and unintentionally crossed an unmarked border.
The three have been held in Tehran’s Evin prison. They have not been publicly charged.
In December, Iranian Foreign Minister Manouchehr Mottaki said they would stand trial, but he did not specify on what charges.
US Secretary of State Hillary Clinton has called on Tehran to free the hikers, and said that any charges would be unfounded.
