Pyongyang: North Korea has described a break-in at its embassy in Spain in February as a "grave terrorist attack". In its first official comment, Pyongyang called for an investigation and said it was closely watching rumours that the Federal Bureau of Investigation (FBI) had played a role, the BBC reported on Sunday.

On Wednesday, Cheollima Civil Defense - a self-styled human rights group - which is committed to ousting North Korean top leader Kim Jong-un, claimed to be behind the raid. The group took computers and data and said it gave its evidence to the FBI - US intelligence agency.
