A preliminary report from WorldnetDaily:
An early morning attack by four gunmen who stormed and reached the emergency-response control room of a secured nuclear facility in South Africa has left one of the plant's operational officers hospitalized and officials with the country's nuclear agency threatening a newspaper with charges of violating national security laws for publishing an account of the intrusion.
I don't know if this is a big deal or not, but hopefully we'll get the full story soon.
