A PROPAGANDA ad campaign toasting Trump and Putin’s friendship has appeared in Montenegro - days after a sinister 'Russian linked plot to kill the nation’s leader' was uncovered.

A billboard poster has been placed on a busy road in the town of Danilovgrad by a shadowy pro-Russian and Serbian group called In4s.

It shows President Elect Donald Trump and Russian leader Vladimir Putin side-by-side with the slogan “Let’s make the world great again - together!”

The website for In4s said that the election of Donald Trump offered hope of a new friendship between America and Russia and avoided war.

It also praised Trump’s comments against NATO.

But tellingly it slammed the previous Barack Obama administration for backing of the “criminal regime of Milo Djukanovic” - who is the Montenegrin prime minister.

This comes just over a week after a Moscow linked militia were accused of conspiring to murder Mr Djukanovic in a sinister bid to curtail NATO power.

Prosecutors in the Balkan state revealed claims that nationalists from Russia hatched a plot to have a sniper shoot dead the leader as part of a coup attempt.

The conspirators are said to want to stop the tiny country – which used to be part of Yugoslavia – from ever joining NATO.

The suspects have been accused of plotting to do this by toppling the pro-Western government and replacing it with a Moscow friendly one.

While the explosive allegations came to light, Russian crack paratroopers poured into neighbouring Serbia for a mission code-named Slavic Brotherhood.

Vladimir Putin’s Russia has been linked to the Montenegro assassination conspiracy because its military leadership favours “hybrid warfare”.

This blend of unconventional and conventional war can involve agents or militias not officially attached to a country’s forces.

Sometimes it aims to create a climate that justifies military intervention.

This underhand technique is said to have been used to seize Crimea from Ukraine in 2014.

Agents are said to have whipped-up tension among Crimeans with Russian heritage and under a pretext of helping them, Russia annexed the Black Sea nation.

As reported on Monday, Trump and Russian strongman leader Vladimir Putin had their first telephone conversation.

Putin wished Trump “success in implementing the election programme” after he was propelled to power by the shock election outcome.

Both agreed to “try to mend ties” and to fight ISIS together.
