ABC: Three Israeli attacks on Sudan, not just one

Exclusive: Three Israeli Airstrikes Against Sudan - Political Radar:

"ABC News' Luis Martinez reports: Israel has conducted three military strikes against targets in Sudan since January in an effort to prevent what were believed to be Iranian weapons shipments from reaching Hamas in the Gaza Strip, ABC News has learned.

Earlier this week, CBSNews.com was the first to report that Israel had conducted an airstrike in January against a convoy carrying weapons north into Egypt to be smuggled into the Hamas-controlled Gaza Strip.

But actually, since January, Israel has conducted a total of three military strikes against smugglers transporting what were believed to be Iranian weapons shipments  destined  for Gaza, a U.S. official told ABC News. 

The information matches recent reports from Sudanese officials of two airstrikes in the desert of eastern Sudan and the sinking of a ship in the Red Sea carrying weapons."

Questions that come to mind: Saudi and Egyptian radars on the Red Sea must have seen planes, how long have they known? What kind of collaboration is there on this? What logistical support from the US?
