I dont they were taken very far..
There have been reports they were kidnapped by the security services themselves.
They couldn't have been taken very far if they remained in Gaza. I was talking about their close proximity to the center or seat of power when they were abducted. Along those lines, though, had not seen reports that someone in the security services kidnapped them, but it wouldn't surprise me if the Palis constantly run "good cop - bad cop" scams.
