The "evidence" was contained in a film aired a few days earlier on Italian TV, which featured three Georgians who said they were part of a group of foreign snipers paid to gun down protesters and police in Kyiv and thus provoke Yanukovych's overthrow, according to BBC.

Italian TV also appeared to suggest that the film called into question the sanctions imposed on Russia over its intervention in Ukraine.

But BBC Monitoring has found evidence casting doubt on the veracity of one of the Italian film's key witnesses.

The film features testimony from three Georgian nationals who say they were brought to Kyiv in the early part of 2014 to act as agents provocateurs. The men suggest they were sent to Ukraine on the orders of former Georgian President Mikheil Saakashvili, and also received instructions from an American sharpshooter.

Two of the men, named in the film as Koba Nergadze and Zalogi Kvaratskhelia, were interviewed by Micalessin in Skopje, the capital of Macedonia.

The third, captioned as Alexander Revazishvili, was interviewed in another eastern European country, which the filmmakers said they had been asked not to identify.

"We were ordered to shoot down both the Berkut and the protesters indiscriminately. That was why I was dumbstruck and shocked," he told the filmmaker.

But there is reason to question whether Revazishvili is telling the truth, BBC Monitoring wrote.

In another part of the film, he refers to the time when he was living in Kyiv with other Georgians who had come to join the Maidan protests. He is shown looking at a smartphone displaying a Russian TV report about the Maidan protests.

"Yes, sure. That's me," he says. "This is the tent where we were living and this is me."

From this footage, it is not possible to say definitively whether this man is Revazishvili or not. The filmmakers do not identify the Russian TV report, but the blurred caption at the bottom of the smartphone screen appears to contain the words "Georgian mercenaries".

This is enough to track down the report via Google. It turns out to be a report published by the pro-Kremlin TV station Life on December 1, 2016, that also features claims that Georgian snipers were responsible for the deaths at the Maidan protests in February 2014, though it does not name them.

The report does not include any further footage of the man Revazishvili claims is him.

But the Life reporter, Semyon Pegov, indicates that the footage shown here and in the Italian film is part of another report which he had made when he was in Kyiv covering the Maidan protests in 2014.

"Clearly, Revazishvili is an unreliable witness," BBC Monitoring says. It also means that the only piece of corroborating evidence adduced by the film to place him in Kyiv at the time of the Maidan protests turns out to be bogus, according to the report.

Monitors draw attention to its connection to former Italian Prime Minister Silvio Berlusconi, a politician known for his friendly relationship with Russian President Vladimir Putin.

"Moscow will be no doubt be hoping that Micalessin's film increases the pressure for the sanctions to be eased or dropped," BBC Monitoring concludes.
