What is this madness about the N. Korean embassy in Spain?

This story is completely nuts. "At least two of the 10 assailants, who beat and interrogated the eight people who were in the [DPRK] embassy, have been identified and have links to the US secret services. Spanish interlocutors have asked the CIA about their involvement" https://t.co/qZEWAbgh0k

Now this sounds batshit crazy!  That's even crazy for a Tom Clancy novel.  No way THIS could be true...
