TEHRAN, Iran (AP) — Iran announced Thursday that Sarah Shourd, one of the three Americans jailed for more than a year, will be released Saturday to mark the end of Islamic holy month of Ramadan.

Spokesman for the Iranian Ambassador to the United Nations tells Fox News that the American hiker will be released “very soon.”

Iran claims they illegally crossed the border from Iraq’s northern Kurdish region and had threatened to put the three on trial for spying. Their families say they were hiking in the largely peaceful region of Iraq and that if they crossed the border, it was accidental.

“The release of one of the detained Americans will be Saturday at 9 a.m. at the Estaghlal hotel.”

The Iranian message gave no other details about who would be freed. But Sarah Shourd, 31, has told her mother she has serious medical problems. Shane Bauer, 27, and Josh Fattal, 27, also are being held.
