Two Americans jailed in Iran were released Wednesday after being held captive for more than two years by the Islamic republic on charges of espionage.

Josh Fattal and Shane Bauer were escorted from Evin prison to an airport in Tehran by a convoy of Swiss and Omani diplomats.

"I have finished the job that I had to do as their lawyer," declared attorney Masoud Shafiei, who successfully obtained the signatures of two judges on a $1 million bail-for-freedom deal.

The hikers were arrested along the Iran-Iraq border in July 2009 and later sentenced to eight years in prison for spying.

A third hiker, Sarah Shourd was also arrested. She was freed last year on bail.

The trio, friends from their days at the University of California at Berkeley, have maintained their innocence and have continually denied the espionage charges against them.

Switzerland represents U.S. interests in Iran since the U.S. has no diplomatic relations with the country. Oman is where the two men will be taken immediately following their release.
