Vladimir Putin’s notorious ‘doomsday radio’ crackled into life with a string of codewords after a suspected Russian missile hit NATO territory in Poland.

The mysterious Cold War relic spewed out a sequence of cryptic messages hours after the incursion,which could further deepen tensions between the military alliance and Moscow.

Volodymyr Zelensky also claimed yesterday that early data suggests Putin deployed a North Korean missile in an attack that killed six people in a Ukrainian village.

The secret cyphers usually make little sense,with the latest series including the words BRIBETAKER,SEXFAT or SEXOFAT,MONARCHIST,MOTEL,MUZOPAYUS,STEPENNY and LEVRETKA.

One message included KLETKA,or ‘CELL’,while another used NEDOTEPA,roughly translating as ‘DIMWIT’.

A Russian missile and drone barrage across Ukraine killed at least 10 civilians,including children,overnight,officials said yesterday.

The radio – on air for half a century and nicknamed The Buzzer – is linked to Russia’s Strategic Forces.The 4625 kHz frequency usually carries a repetitive buzzing sound,but when a message is sent,the buzzing stops and a ghostly operator reads out codewords in Russian.The purpose of its messages remains unclear,but they tend to appear at times of high tension. It is widely believed to form part of a Russian military command-and-control network,allowing instructions to be transmitted to designated units through one-time codes.The precise operator and purpose have never been officially disclosed.Bursts of activity may indicate military exercises,readiness tests or operational communications.Get in touch with our news team by emailing us at .For more stories like this,check our news page.
