U.S. intelligence has declassified intriguing information regarding the assassinations of Putin's rivals.

The American intelligence has declassified part of a report detailing the targeted assassinations of political opponents of Russian President Vladimir Putin. Several of these killings were personally sanctioned by Putin.

"First, Russian politician and fierce Kremlin critic Boris Nemtsov was shot dead in Moscow. Then, former Putin's media mogul Mikhail Lesin died in Washington. Later, police stated he died from blunt force trauma after falling multiple times in a hotel room,” — writes Bloomberg.

The intelligence report, partially declassified at the request of a journalist from the publication, also mentions other deaths of Putin's adversaries. The document notes that the Kremlin systematically employs intelligence services to eliminate those deemed threats to its regime.

The report names several high-profile cases:

In 2004, the former head of the Chechen Republic of Ichkeria Zelimkhan Yandarbiyev was killed in Qatar. The assassins, Russian GRU agents Anatoly Bilashkov and Vasily Bogachev, were sentenced to life imprisonment by a Qatari court, but were soon extradited to Russia. It was expected that they would serve the remainder of their sentence in a Russian prison; however, by 2005, the Federal Penitentiary Service stated that it had no information on the whereabouts of Bilashkov and Bogachev.

In 2006, former FSB officer Alexander Litvinenko was poisoned with radioactive polonium in London. British investigators established that the direct executor of Litvinenko's assassination was Russian Federal Protection Service officer Andrei Lugovoy, who later became a member of the State Duma.

In 2012, Russian businessman Alexander Perepilichny died in Britain, considered one of the key informants in a case regarding possible money laundering by Russian officials in Europe. His death occurred shortly before he was scheduled to testify about this in court. The U.S. intelligence report indicated that he was poisoned.

In 2015, Lugansk militant Alexander Bednov was killed during an attack on an armored bus he was traveling in. U.S. intelligence suspects that he and several leaders of Donetsk and Lugansk separatists were murdered on Kremlin orders to strengthen Russia's control in the region.

"Such assassinations are highly likely to continue,” — emphasized U.S. intelligence.

As reported by "Telegraph," U.S. intelligence indicated that Russia plans sabotage against American and European defense companies. The Russian regime's intelligence services are attempting to recruit employees from the United States defense industry.
