North Korea has broadcast a ‘coded message’ to sleeper agents on state radio – sparking fears of an imminent attack.
The announcement was made as part of a cryptic broadcast and analysts believe it is a ‘book cipher’ for agents in foreign countries.
The radio announcer said: ‘(I’m giving) chemistry review work to No 21 expedition agents,’ before continuing with the numbers, which spies can decode using a reference book.
Similar broadcasts were reportedly made on November 6 and 11 and the latest is the 14th since June.
A source in the South Korean ministry told the Daily Star that their neighbours could launch an attack ‘at any time’.
They have also detected many missiles moving around the country.
