The Sudanese government is blaming Israel for what it says was the bombing of an arms factory in the capital.
Sudan Information Minister Ahmed Balal Osman says he believes Israeli warplanes caused explosions and a huge fire at the Yarmouk manufacturing complex in Khartoum.
There has been no comment from Israeli officials.
Witnesses told a VOA reporter they saw two planes fly over the facility shortly before the blasts late Tuesday.
"What they say is that the plane, the first plane, shed light on the area and then it was followed by the sound of a rocket and then an explosion," said VOA reporter Ismail Kushkush.
Sudanese officials say there were no casualties. Kushkush reports that according to local residents, at least one person was killed by shrapnel that fell on his home.
Sudan has blamed Israel for previous airstrikes and explosions in the country. Israel has not commented on the accusations.
