Plans for the attack emerged after a US spy plane discovered scores of acoustic sea-mines had disappeared from a naval base in North Korea.

I'm no expert, but isn't it just as likely that the mines were just moved somewhere else?

. . . acoustic sea-mines . . .

The kind that make noise?

Yes, it's just as likely...unless a US Navy P-3 Orion discovered those mines in the Straits of Gibraltar.

Again, just my opinion. But confirmation is generally key to releasing intel.
