Makes sense.

"... At any rate, when I first heard of the flight from Bagram landing in Iran, I immediately began to wonder whether there might be some sort of prisoner exchange taking place. After all, the US still has a number of international prisoners housed at Bagram. With the situation on the ground in Afghanistan looking increasingly shaky, the disposition of these prisoners could be one of the most difficult aspects of a hasty retreat from Afghanistan should the US decide not to leave a small force there after the end of this year.So, is it possible that the landing in Bandar Abbas was actually staged so that some of these prisoners could be dropped off? If so, the cryptic announcement of new fighters being arrested in Iran could fit pretty closely with that event. It is a bit more difficult to account for the announcement saying that Afghans as well as Pakistanis were part of the arrests. The official story is that the US no longer holds any Afghan prisoners at Bagram, but the US has long played shell games with prisoners there, so they would be motivated to make any actual Afghan prisoners disappear quietly. [And note this report by Spencer Ackerman where it seems that the foreign prisoners held by the US at Bagram seem to have at least some communications with Afghan prisoners so that hunger strikes spread between the two populations.]..."
