Ahmadinejad has said Shourd was being released on compassionate grounds. Her mother says she has serious medical problems, including a breast lump and precancerous cervical cells.

Shourd's release, some analysts say, could be used by Iran as a way to deflect the international outcry over a stoning sentence for a woman convicted of adultery and the continued crackdown on opposition groups, which led two Iranian ambassadors in Europe to quit this week and seek asylum.

"Ahmadinejad is possibly trying to make the environment less hostile in New York," said Rasool Nafisi, a researcher on Iranian affairs at Strayer University in Virginia.

Even in the last minutes, Ahmadinejad tried to put his stamp on the release. His adviser on women's affairs, Maruyam Mojtahedzadeh, was on hand to greet Shourd at Tehran's Mehrabad Airport.

In a statement to Iran's state-run Press TV before boarding the flight to Oman, Shourd thanked Ahmadinejad and other Iranian leaders for "this humanitarian gesture."

"I want to really offer my thanks to everyone in the world, all of the governments, all of the people, that have been involved," added Shourd, wearing a maroon headscarf and a tan coat.

Upon arrival in Oman, Shourd also thanked the sultan for his help and said she would turn her efforts to trying to win the release of her companions. Her immediate travel plans were unclear. A US official said she would be in Oman for at least a day.

Shourd, who grew up in Los Angeles, Bauer, who grew up in Onamia, Minn., and Fattal, who grew up in Elkins Park, Pa., were detained on July 31, 2009, and accused of illegally crossing into Ir outside the gray walls of Evin Prison, it was unclear whether the opening for her release could just as suddenly close.

A day earlier, a commentary by a news agency linked to the Revolutionary Guard called the bail an insult to Iran's security and intelligence forces. Shourd's family then said they couldn't afford the amount and the State Department noted it would not offer financial help.

Then came the unexpected news from Tehran's chief prosecutor, Abbas Jafari Dowlatabadi, that bail had been paid to Iran's Bank Melli in the Omani capital Muscat. Shourd's family has not disclosed the source of the funds, opening speculation that a diplomatic pact was cut with Oman.

A US official said neither the US government nor the families of the hikers put up the money, but could not say who else might have paid it.

All signs pointed to Oman, both a close Western and Iranian ally that wraps around the southeast corner o the role that Oman has played."

He could not say if any money had changed hands in winning Shourd's release, but noted that "arrangements were made that satisfied Iranian requirements under their judicial system."

At the same time, Crowley said the US government had no information to suggest any US or international sanctions on Iran had been violated.

"I am very pleased that Sarah Shourd has been released by the Iranian government, and will soon be united with her family," Obama said in a statement.

Shourd's mother, Nora, said she has hoped and prayed for this moment for 410 days.

"Sarah hao make sure that she now gets the care and attention she needs and the time and space to recover," she said. "I can only imagine how bittersweet her freedom must be for her, leaving Shane and Josh behind."
