Some U.S. media outlets, citing sources whose names were not disclosed, reported on a rare and important trip by John Ratcliffe, head of the Central Intelligence Agency of the United States, to Russia.

CBS News and Axios have reported on this important trip, but they did not announce the trip’s objectives or which people the CIA chief would meet in Russia.

Yesterday, a video was released with the explanation that a Boeing C-17 Globemaster III transport aircraft belonging to the U.S. Air Force landed at Vnukovo Airport in Moscow.

Based on flight data, the aircraft departed from Riga, the capital of Latvia, bound for Moscow, and its recent flight records show a stop at Camp Springs in the state of Maryland—an installation where U.S. presidential special aircraft are stationed.

So far, U.S. officials have not commented on the matter. In contrast, Dmitry Peskov, the Kremlin spokesperson, has neither confirmed nor denied the report, but told Reuters that Vladimir Putin has no plans to meet with John Ratcliffe.

Reuters has predicted that one of the focal points of these talks could relate to Iran and Russia’s military support for Iran.
