Please, go away (or don't move through my hex!)

The user manual says on Interdiction ...

"As units move on the map in Travel or Rail Mode, there is a chance that their movement will be Interdicted by enemy air units. [...] If Interdiction occurs, then an Air Strike occurs against a unit in the target hex [...]."

Note that it doesn't say that the unit being targeted is the one that triggered interdiction in the first place. Just "a unit".
