JERUSALEM, Oct. 25 (Xinhua) -- Israeli Prime Minister Benjamin Netanyahu on Thursday said Israel had nothing to say about Wednesday's explosion at an arms factory in Khartoum, Sudan.

Israel officially has no comment on the event, the prime minster said at a joint press conference with visiting Italian Prime Minister Mario Monti in Jerusalem.

Defense Minister Ehud Barak reiterated Netanyahu's response, telling Channel 2 news that there is "nothing to say" about this topic.

On Wednesday, Sudanese officials claimed the Israeli Air Force bombed the munitions plant, which caused secondary explosions and a massive blaze.

Sudan called on the United Nations Security Council to condemn Israel for the attack, in which two people were killed.

An Israeli foreign ministry spokesperson told Xinhua Wednesday that they are unaware of the allegations.

A ministry source told The Jerusalem Post that Sudan had a " tendency" to blame Israel for a number of recent untoward events.

In May, the Sudanese government blamed Israel for a mysterious explosion in the eastern city of Port Sudan in which one person died, as well as a missile attack in 2011. In 2009, Khartoum said Israel was behind an air strike on a suspected weapon-smuggling convoy. But Israel declined to comment on any of the incidents.

The eastern part of Sudan has allegedly been using for a long time as a trail for weapon smuggling, often via the deserts of Egypt's Sinai Peninsula into the Hamas-ruled Gaza Strip.
