The Iranian regime, both as you said and its media has said publicly, doesn't want to exert pressure on the European government not to accept that. Let me give you the background very quickly.
Back in September 2011 the UNHCR announced that all residents of Ashraf are asylum seekers and enjoy international protection, but Iraq did not allow them to have the interview for several months. It took six months before they could do the interview. As you said, they told the residents this was a temporary location and they would immediately be relocated. Even they said that this would be a revolving door, that people would go from Ashraf to Liberty outside Iraq.
They said that when 400 people went from Ashraf to Liberty, by the time they were relocated outside Iraq, then the next group could go, but as you know, after two years, only 10% have gone.
Albania has taken 240. Over 90 people have gone to Germany, and a few have gone to other European countries.
I think the UNHCR could have expedited the process by announcing right from the beginning that all these people were refugees. On the other hand, the Iranian regime is actively preventing that.
The regime's objective is really to kill these people in liberty.
