From CBS News, March 25, 2009, by Dan Raviv, CBS News correspondent in Washington:
...CBS News national security correspondent David Martin has been told that Israeli aircraft carried out [an airstrike in Sudan this past January, said to have been "in a desert area northwest of Port Sudan city, near Mount al-Sha’anoon," according to SudanTribune.com; in which 39 people riding in 17 trucks were reportedly killed].
Israeli intelligence is said to have discovered that weapons were being trucked through Sudan, heading north toward Egypt, whereupon they would cross the Sinai Desert and be smuggled into Hamas-held territory in Gaza.
[Sudan has become one of the favorite smuggling routes for Iranian intelligence, with arms from Revolutionary Guard bases going through Sudan to Egypt, and then reaching Gaza via the Sinai desert and the underground tunnels at the Philadelphi Route.]
In January, the U.S. signed an agreement with Israel that calls for an international effort to stop arms smuggling into Gaza.
...The first government official in Sudan to talk about [the attack] was the state minister for highways, Mabrouk Mubarak Saleem, who said: "A major power bombed small trucks carrying arms – burning all of them. It killed Sudanese, Eritreans, and Ethiopians and injured others."
...If Israeli airplanes carried out the attack in Sudan, it would suggest that there is a shadow war against Hamas and its weapons sources that is wider than the Israeli or U.S. government has revealed.
