Sudan has accused Israel of bombing a military factory and has threatened retaliation after the attack.
Minister of Information Ahmed Belal Osman told reporters Wednesday that four airstrikes struck the Yarmouk Complex, south of the capital of Khartoum, causing an explosion that rocked the capital just before dawn.
"We think Israel did the bombing," Osman told a news conference. "We reserve the right to react at a place and time we choose."
He said four aircraft were involved in the attack, which occurred at about midnight Tuesday.
Evidence pointing to Israel was found among remnants of the explosives, he claimed.
Residents had said that an aircraft or missile flew over the factory shortly before it exploded and burst into flames.
Some people were hospitalized because of smoke inhalation but there were no casualties reported.
The sprawling Yarmouk facility is surrounded by barbed wire and set back about two miles from the district's main road.
A source familiar with the Yarmouk factory told the AFP that its main compound and storage area had not been damaged.
