South Korea's Yonhap news agency is reporting a huge explosion shook North Korea's northernmost province on Thursday producing a mushroom cloud over two miles (4 km) wide.
The blast coincided with the anniversary of North Korea's founding on Sepember 9 when various military activities are staged.
The New York Times reported on Saturday that U.S. President George W. Bush and his top advisers recently received intelligence reports that could indicate North Korea is preparing its first nuclear test, citing senior officials with access to the intelligence.
Yonhap reported the explosion happened in Yanggang province along the Chinese border, the site of Yongjori Missile Base -- a large facility with an underground missile firing range.
According to data gathered by Nuclear Threat Initiative (NTI), Yongjori is a suspected site for North Korea's uranium enrichment program.
These facts lead US intelligence to the following conclusion:
The U.S. official said the cloud could be the result of a forest fire.
Yes, a 2 mile wide mushroom cloud at a missile testing site near a nuclear development program is a forest fire.
Thank god we have Bush's intelligence people keeping us informed and safe.
