A dissident group accused of breaking into North Korea's embassy in Madrid said on Thursday it was temporarily suspending operations, after a Spanish judge issued international arrest warrants for two suspected intruders now believed to be in the United States.

A shadowy group called Cheollima Civil Defense, also known as Free Joseon, acknowledged on its website late on Tuesday that it was behind the incident but said it was not an attack and that the group had been invited into the embassy.

In a statement on its website on Thursday, Cheollima Civil Defense said that while it has "bigger tasks ahead," it had temporarily suspended work because of "speculative" media reports.
