Sudan said on Tuesday that Iran has no link to the military factory that it claims was struck in an Israeli airstrike.

Israel has neither confirmed nor denied involvement in last week’s explosion at the factory, which destroyed much of the complex and killed four people in the Sudanese capital. But Israeli officials have claimed that Sudan is playing a key role in an Iranian-backed network of arms shipments to Hezbollah and Hamas.

The Sudanese Foreign Ministry accused Israel of leaking “misleading information” about Iranian support for weapons production at the Yarmouk factory.

It said in a statement late Monday that “Iran does not need to manufacture weapons in Sudan, be it for itself of for its allies.”

Two Iranian warships docked in Port Sudan several days after the blast, triggering speculation the events were related. Sudan denied this, saying the warships were on a “routine” visit.

The two ships – a helicopter carrier and a destroyer – departed on Wednesday after a four-day stay, according to Reuters.
