NORTH Korea's state radio station has begun broadcasting mysterious number codes believed to be messages to spies embedded in Western nations like Britain.

Radio Pyongyang - which usually plays non-stop propaganda - started broadcasting apparently nonsense messages just after midnight this morning.

A series of numbers and peculiar gibberish is being relayed over the airwaves of the North Korean station, observers of the secretive state can reveal.

The female radio announcer said: "We give review work in metal engineering to No. 27 expedition agents", the Korea Times reports.

This bizarre phrase has been heard on at least one occasion before.

Since June 24, Kim Jong-Un’s secret service has broadcast 13 encrypted number announcements.

In July the female broadcaster said: "Now we'll begin a mathematics review assignment for members of the 27th expeditionary unit of the distance learning university.

"Turn to page 459, question 35; 913, question 55; 135, question 86."

It is believed the mysterious numbers can be deciphered by North Korean spies who have a special reference book.

The technique dates back to the Cold War when shortwave bands were full of bizarre transmission called “numbers stations”.

But now paranoid spy handlers have resorted to using them again because internet and phone messages can be monitored easily.

Elsewhere numbers station coded messages are being transmitted from secret locations in Ukraine – part of which Russia invaded last year after coup that brought a pro-EU government to power.





Poland is another spot where the messages are being transmitted from and a country now at the centre of row that some fear could spark a war in Europe.

Tensions are already running high on the divided peninsula after North Korea carried out its fifth nuclear test in September.

And the unsuccessful launching of two Musudan intermediate-range ballistic missiles was internationally condemned.

It emerged today that the US State Department is urging people not to go on holiday to sanction hit North Korea - because the cash they spend is bankrolling Jong-un’s bid to become a nuclear warlord.
