Ned Prince, US State Department’s spokesman denied having a previous agreement on the swap and said that Iran’s statements are an “outrageous effort” to deflect blame for the current deadlock of the JCPOA on the US.
The spokesman for the Iranian ministry of foreign affairs, Saeed Khatibzadeh said on his Twitter account that the real outrageous action is that of the US.
"Outrageous"=the US denying simple fact that "there IS an agreed deal on the matter of the detainees." Even on how to announce it.
Humanitarian swap was agreed with US & UK in Vienna-separate from JCPOA- on release of 10 prisoners on all sides.
