Iranian officials said they will release Sarah Shourd, one of the three American hikers captured more than a year ago, to mark the end of the Islamic holy month of Ramadan.

Authorities arrested Shourd, Shane Bauer, and Josh Fattal in July 2009, accusing the Americans of entering Iran illegally and having ties to U.S. intelligence.

Their families said the trio was hiking in northern Iraq when they unintentionally crossed an umarked border.

Iranian officials said they would release Shourd at 9 a.m. on Saturday at the Estaghlal hotel, the same place where the prisoners' mothers were allowed to visit them in May.

Upon hearing the news of her daughter's pending release, Nora Shourd remained silent, only saying,"I'm happy."

Shourd's mother was the last person to have contact with any of the prisoners. She reportedly spoke with her daughter on the phone for three or four minutes on Aug. 2.
