A mysterious underground organization tied to the February break-in at the DPRK embassy in Madrid on Sunday urged international press to cover the "verifiable facts" and promised a major event.

In a statement by the Cheollima Civil Defense group, also known as "Free Joseon," released on its website at 2225 UST, the organization promised to work for the "dismantlement of prison camps" in North Korea and support "reform and opening" in the country.
