One of three U.S. hikers detained in Iran for more than a year is to be freed on Saturday, the Ministry of Culture and Islamic Guidance told AFP Thursday.

In a brief message, the ministry said: “Freedom of one of the American detainees on Saturday 20th of [the Iranian month of] Shahrivar at 9:00 am [local time] at Hotel Esteghlal.” The hotel is situated in Tehran.

Iran is currently holding three U.S. hikers in custody after they strayed into the country from across the border with Iraq more than a year ago.

Shane Bauer, 27, Sarah Shourd, 31, and Josh Fattal, 27, have been accused by Iranian authorities of spying and of illegally entering Iran.

The three insist they entered the Islamic republic by mistake after becoming lost during a hike in Iraqi Kurdistan, while U.S. authorities say they are innocent and should be released immediately.

The ministry usually uses text messages to inform the media or invite it for any news events to be reported.
