http://www.smh.com.au/articles/2004/09/14/1094927561833.html?oneclick=trueNorth Korea has invited a British diplomat to visit the site of an explosion that shot a huge mushroom cloud into the sky to verify claims that it was the planned demolition of a mountain for a hydroelectric project.
Experts from the United States and elsewhere say they don't believe Thursday's blast near the Chinese border was a nuclear test. But a Bush administration official said the United States has indications the North is trying to conduct one.
North Korea denounced the speculation over a nuclear test as part of a "preposterous smear campaign" aimed at diverting world attention away from revelations about past South Korean nuclear activities, Pyongyang's official KCNA news agency said.
Speaking on the condition of anonymity, a US official said it isn't clear what happened. While the official said there isn't any reason to believe it was a nuclear test, the official also couldn't confirm the North Koreans' explanation today that it was linked to construction of a hydroelectric project.
A UN official said the Comprehensive Nuclear-Test-Ban Treaty Organisation, which monitors nuclear activity, had not picked any signs that the explosion was a nuclear blast.
The North's official news agency KCNA said "blastings at construction sites of hydro-power stations in the north of Korea" had taken place.
North Korean Foreign Minister Paek Nam Sun told the same to visiting British Foreign Office minister Bill Rammell.
