I find it hard to believe that Iran would let Israeli prisoners be transferred to its territory. They need plausible deniability.
These are certainly worrying developments, but AFAIK, so far, other states in the region aren't speaking out forcefully in an attempt to get Israel to stop. If/when they do, it'll get much more difficult for the various governments to stand down without a larger conflict.
Cheers,
Scott.
