According to El Pais, at least two out of 10 attackers were identified to have connections with US intelligence services. Spanish investigators have already requested the CIA about their involvement in the incident.
According to the publication, the CIA denied their guilt, but the response to the request was "unconvincing."
This incident may eventually lead to diplomatic friction between Madrid and Washington, the newspaper said. Sources in the Spanish government believe that if the CIA’s involvement in the attack is confirmed, it will be regarded as "unacceptable" actions by the ally. According to the publication, this would mean that US intelligence services acted in Spain without permission and violated international agreements protecting diplomatic missions.
The reports come after in February, El Confidencial newspaper reported, citing sources in the Spanish Interior Ministry, that a group of unidentified men broke into the North Korean embassy in Madrid, restrained the diplomatic staff for several hours and stole computers. According to the newspaper, the incident occurred on February 22. One of the employees managed to escape and report to the police.
