We may have negotiated the release of 4 of our countrymen by promising the Iranians seven sanctions violators in return, but that doesn't mean Iran is getting those seven nationals back.
Although all of the Iranians were given the green light to return to their country - flights were even booked for them out of Switzerland, where the US and Iran made the "prisoner swap" on neutral ground - but three of the Iranians being held by the US have chosen to stay here. The other four never made it to their flight in Geneva.
None of the Iranians freed in the prisoner swap have returned home and could still be in the United States, it has been reported.
The seven former inmates, who were released as part of a deal with the Islamic republic, did not show up to get a flight to Geneva, Switzerland, where the exchange was set to take place on Sunday.
