Opposition sources in Sudan claim that the arms factory bombed overnight Tuesday in south Khartoum, the Sudanese capital, belongs to Iran's Revolutionary Guard.

At this point, it is difficult to verify these claims since it isn't even clear who stands behind the bombing. Sudan's Information Minister Ahmed Belal Osman claimed that four Israeli planes are responsible for the bombing of the Yarmouk Military Industrial Complex in southern Khartoum. "They came from the east," he said. "You know that last year, and the year before that, Sudanese citizens were attacked in the Red Sea... it all point to Israel's involvement."

However, what was not said by the Sudanese authorities, who provided a plethora of confusing and conflicting reports (even regarding the number of casualties), was information regarding the factory itself. In recent years, several reports published in the Arab media said that Iran's Revolutionary Guard built weapons manufacturing plants together with the Sudanese government.

However, their military cooperation does not end with the establishment of one military plant, and even senior Sudanese officials have not denied in the past that Iran has military factories on their land.

In fact, according to foreign reports, the arms factories that Iran built in Sudan were meant to arm Hamas. In the past, European media reported that Iran has sent men from the Republican Guard in order to train the Sudanese army.

Moreover, after the fall of the regime of Libyan leader Muammar Gadhafi, the Al-Quds Force of the Iranian Revolutionary Guard Corps succeeded in smuggling dozens of antiaircraft and SA-24 missiles from the Libyan army's crumbling arsenals to Sudan, in order to later pass them on to Hamas.

One of the reports said that these missiles are held in a military facility in north Darfur which is controlled by the Revolutionary Guard.

The bombing of the military factory in Khartoum took place after midnight on Tuesday. Initially, senior officials in Sudan claimed that the explosion was the result of an accident that occurred during routine maintenance. However, residents in the area told the Sudan Tribune, which is located outside of Sudan, that they heard a sound similar to that of a missile, and then several seconds later they heard a big explosion. It was also reported that at least two people were killed in the blast and eyewitnesses reported seeing a big crater in the facility.
