Did the KGB kill Kennedy?

The Herald reports:

Lee Harvey Oswald met a senior KGB agent months before the assassination of John F Kennedy, documents from the newly-released trove have revealed.

Oswald met agent Valeriy Vladimirovich Kostikov in Mexico City’s Soviet embassy two months before the president was shot and killed in Dallas on November 22, 1963, the Daily Mail reported.

Kostikov was a senior agent in the 13th Department which was responsible for assassinations.

That’s a mighty big coincidence.
