DETAILS OF FIVE AMERICANS RELEASED BY IRAN:
JASON REZAIAN
The Washington Post's bureau chief in Tehran was detained in July 2014 and jailed in Tehran's Evin prison. Iran accused Rezaian of espionage and other charges. Iran announced earlier this year that Rezaian had been sentenced but never revealed the length of the sentence.

Hekmati, 32, was convicted of spying, a charge his relatives and the US deny. He was sentenced to death, but that was commuted to a 10-year prison term.
SAEED ABEDINI
The 35-year-old Iranian-American pastor from Idaho was sentenced to eight years in prison in 2013 after being accused of harming Iran's national security by setting up home-based churches in his native country. Abedini and his wife regularly travelled to Iran on Christian mission work until 2009. He was setting up an orphanage in the country in 2012 when Iranian authorities detained him.
Republican presidential candidate Ted Cruz has urged Obama to secure Abedini's release and appeared with his wife, Naghmeh, at campaign events. Naghmeh Abedini said last week in a Facebook post she had "no updates from Saeed for the last two
