Five Americans freed from Iranian detention this week returned to US soil early Tuesday following an initial stop in Doha, Qatar, two US officials told CNN.

Emad Shargi, Morad Tahbaz and Siamak Namazi, along with two Americans who have not been publicly named arrived at Fort Belvoir’s Davison Army Airfield for an emotional reunion with their family members.

The freed Americans, who were released Monday as part of a wider deal that includes the US unfreezing $6 billion in Iranian funds, will have the option to participate in a Department of Defense program known as PISA (Post Isolation Support Activities) to help them acclimate back to normal life now that they are back in the United States.

The return of the five Americans, all of whom had been designated as wrongfully detained, caps a significant diplomatic breakthrough after years of complicated indirect negotiations between the US and Iran, who do not have formal diplomatic ties.
