Israeli airstrikes against Sudan plant?

Looks like four f-15s performed a “surgical” in a military plant in Sudan. Wiki has a few info and links. http://en.wikipedia.org/wiki/2012_Sudan_airstrike
…but no confirmation by official israeli sources yet AFAIK.

Debka has an interesting scenario with little or no proof as usual:

Now, the scenario may be simply propaganda, but the really interesting part is:

If Indeed Israel was responsible for the bombing raid, it is possible to postulate the following objectives:
1. Its air force flew 1,800-1,900 kilometers to reach the Sudanese arms factory, a distance longer than the 1,600 kilometers to the Iranian underground enrichment site of Fordo. This operation may have been intended to show Tehran that distance presents no obstacles to an Israeli strike on its nuclear program.
2. The IAF has an efficient in-flight refueling capability.
3. The raid would have degraded Iran’s ability to retaliate for a potential Israel or US attack.
