PYONGYANG - The Democratic People's Republic of Korea (DPRK) Wednesday rejected reports by some US media that Pyongyang is pushing forward her "biological weapons development program" amid its development of weapons of mass destruction (WMD) capacities.

The Director of Press of the Institute for American Studies of the DPRK Ministry of Foreign Affairs said in a statement that such accusation is another example of the US habit to pander fiction as "truth".

"It is the US that conducts military aggressions and cruise missile attacks on sovereign states in broad daylight while faking 'possession of WMD' and 'use of chemical weapons' of those countries," said the statement.

It recollected when US troops openly used biological weapons during the Korean War and inflicted needless suffering on innocent civilians.

"They are also the American politicians and the white supremacists making conceived attempts for state terrorism and racial extinction through overt research and development of the biological weapons in the worldwide-scattered US laboratories," it said.

The US daily Washington Post said this month that US intelligence officials sent a report as early as 2006 to US Congress, warning secret work was underway on a biological weapon in DPRK. The report was widely relayed by other US media outlets.
