Iran moves toward freeing 5 US citizens, including 4 held in infamous prison, in rare deal

After months of quiet negotiations, Iran and the U.S. have reached an agreement that would see four American citizens considered to be unjustly detained released from prison, ABC News has learned.

A lawyer representing one of the detainees tells ABC News that the four were released from Iran’s notorious Evin prison on Thursday and are currently under house arrest in the country. The White House has not yet confirmed their release.

The move sets the stage for what a person familiar with the negotiations described as “a process” that — if all goes well — could ultimately see the four freed along with a fifth U.S. national who was already under house arrest.

The detained U.S. citizens include Siamak Namazi, Emad Shargi and Morad Tahbaz, as well as a fourth who asked that their identity not be made public.

If they are ultimately allowed to leave Iran, the Biden administration is expected to then approve the release of roughly $6 billion worth of Iranian assets held in a restricted account in South Korea due to U.S. sanction laws.

A source familiar with working plans said the U.S. would mandate that the money go toward humanitarian causes, although it’s not yet clear how the administration would enforce any restrictions.

The U.S. and Iran have not had formal diplomatic ties since 1980, and all official communication between the countries is conducted through indirect channels.

A completed deal would mark an uncommon agreement in the long-standing adversarial relationship between Iran the U.S. that has only grown more contentious in recent years.

It would also be the first time Tehran has approved a mass release of U.S. detainees since early 2016, when a prisoner swap coincided with the implementation of a landmark nuclear deal.

Namazi, Tahbaz, and Shargi were all accused of espionage by Iran — charges that the U.S. calls baseless. The three have spent years behind bars in Iran’s Evin prison, infamous for its human rights abuses and as a symbol of the regime’s authoritarian power.

Namazi, 51, was detained in 2015 during a business trip to Iran. When his father, Baquer Namazi, journeyed to the country to attempt to see him, Baquer Namazi was jailed, too.

The elder Namazi was later released from prison but barred from exiting the country. In October, the government finally allowed the then-85-year-old to leave Iran so he could seek medical care. Officials also granted his son a brief furlough to visit with him.

After a little more than a week, the younger Namazi was forced to return to prison. He marked the seventh anniversary of his detention in early 2023 with a seven-day hunger strike intended to urge the Biden administration to do more to free Americans imprisoned in Iran.

Tahbaz, 67, an Iranian American conservationist who also holds British citizenship, was arrested in 2018 and soon after sentenced to 10 years in prison. He was granted a brief furlough in March, when Tehran approved the release of two other foreign nationals, but ultimately forced to return to Evin.

Shargai, 58, was traveling in Iran with his wife in 2018 when he was detained without explanation. Iranian authorities initially confiscated his American passport, inhibiting him from leaving the country, before re-arresting him in 2020 and handing down a 10-year sentence for espionage.

Family members of all three prisoners said that the men have had to endure solitary confinement and inhumane treatment and that they feared for their loved ones’ safety when a massive fire tore through Evin in October.

While the agreement would be a notable achievement for the Biden administration’s efforts to bring wrongfully detained Americans home, it does not include any terms related to Iran’s nuclear program, which the United Nations’ atomic watchdog organization reports has been rapidly expanding in recent months.

In 2018, then-President Donald Trump exited a major nuclear agreement with Iran known as the Joint Comprehensive Plan of Action.

When Biden entered office, his administration promised to broker a “longer and stronger” version of the pact but has so far failed to strike any agreement limiting Iran’s nuclear program.

Nuclear negotiations and talks aimed at securing the release of detainees have taken place on separate tracks, but their positive results have often aligned during periods when Washington and Tehran have displayed an increased willingness to cooperate.

However, there’s currently no indication that the latest round of talks will yield any progress on the nuclear front.
