The Iranian government has announced plans to try three Americans detained after mistakenly hiking into Iran earlier this year. It’s unclear when the trial will begin or what charges will be applied. Last month an Iranian prosecutor accused the three of espionage. On Monday, Secretary of State Hillary Clinton rejected Iran’s charges.

Secretary of State Hillary Clinton: “The three young people who were detained by the Iranians have absolutely no connection with any kind of action against the Iranian state or government. In fact, they were out hiking and unfortunately, apparently, allegedly walked across an unmarked boundary. We appeal to the Iranian leadership to release these three young people and free them as soon as possible.”

Iran’s announcement comes days after it called on the US to release eleven Iranian citizens it says are jailed in US prisons.
