Russia has pre-emptively denied ties to any plot to assassinate late President John F Kennedy ahead of the expected release of thousands of archived records.
The National Archives was due to release a trove of documents related to the 22 November 1963 assassination on Thursday.
One of several conspiracy theories about Mr Kennedy’s killer Lee Harvey Oswald is that he was in contact with then-Soviet intelligence services, or was given training by them while he was on a visit to the USSR.
Russian Foreign Ministry Spokeswoman Maria Zakharova said: "If even here wild insinuations are hurled at Russia, that would be a shame, because it is information, and not disinformation that people want.
"I can’t even imagine how one can distort this topic to such a degree," she reportedly said, despite no official accusations have been voiced publicly by the US government or police authorities.
The majority of the records relating to the case - about 88 per cent - have been available to the public since the late 1990s.
Like a July 2017 release of documents relating to the tragic event, these documents will be posted at the agency's website.
We'll be posting the link to the files when they're live. For now you can go to: https://www.archives.gov/research/jfk, where they will eventually be published.
It is expected that this latest release will contain more information about Oswald and his life in the months leading up to the assassination in Dallas, Texas, including a trip he took to Mexico in September 1963.
It will contain at least 3,000 files, each of which could have hundreds of documents.
