Five Americans jailed in Iran are expected to fly home as part of a deal mediated by the Gulf state of Qatar.

The four men and one woman, who also hold Iranian passports, will board a plane once it is confirmed that $6bn (£4.8bn) in Iranian funds once held in South Korea have reached banks in Doha.

This is part of a deal reached last month after a year of indirect talks.  Five Iranians imprisoned in US jails, mainly on charges of violating US sanctions, will also be released.

The Americans detained in Iran’s notorious Evin prison were told many times before they would soon be freed. Now it seems that will finally happen on Monday morning. They are reported to include 51-year-old Siamak Namazi; 59-year-old businessman Emad Shargi; and 67-year-old environmentalist Morad Tahbaz, who also holds British citizenship.
