It recalled that the opposition parties, many civic and public organizations and non-governmental experts of south Korea are now repeatedly refuting and raising doubts about the "results of investigation" published by the Lee Myung Bak "government" as regards the case.

The letter cited facts to prove the injustice of the "story about a torpedo attack," in particular.

The letter went on:

South Korean non-governmental experts assert that the warship's stranding was the main factor of its sinking as the military authorities reported right after the incident took place.

In the West Sea of Korea, the scene of the warship sinking, a submarine of the U.S. navy once collided with a fishing boat, the letter noted, adding that the south Korean people keep expressing suspicions that the warship "Cheonan" might collide with a submarine of the U.S. forces.

Recalling that the DPRK is urging the south Korean "government" to accept its proposal for dispatching its inspection group, the letter continued: As even those concerned with the six-party talks are expressing their divergent views on the case, it is a natural order of work to make a scientific and objective clarification of the cause of the case if the UNSC is to discuss the said case.

If the UNSC adopts a resolution or a presidential statement and others critical of the DPRK without scientific and objective grounds, this will seriously infringe upon its impartiality and result in disturbing peace on the Korean Peninsula and in the rest of the world, the letter stressed.

On June 11, the south Korean Citizens' Solidarity for Democratic Society also sent a similar letter to the UNSC.
