The CIA declassified data on a possible clash between the USSR military and aliens

The CIA released a previously classified report about a possible meeting of the Soviet military with a UFO and an alien attack on soldiers. About this informs Fox News.
The material suggests that the incident took place between 1989 and 1990, and was first made public in 1993. Currently the document published on the website of the US Central Intelligence Agency. The report describes an alien attack in response to Soviet soldiers shooting down a UFO that flew over a military base.
It is reported that the aliens came out of the wreckage, merged into one object, which “exploded” with a bright light. After that, all but two soldiers “turned into stones.” Allegedly, this information is contained in the report of the State Security Committee of the USSR.
“If the KGB dossier is true, this is an extremely dangerous case. The aliens have weapons and technology beyond our imaginations. They can stand up for themselves if attacked.” – an unnamed representative of the CIA is quoted in the document.
The report said that US intelligence had received reports of a “low-flying saucer-shaped spacecraft” over a Soviet training unit. For unknown reasons, the Soviet military launched a surface-to-air missile at the object, after which it fell near the base.
The document described how “five short humanoids with large heads and large black eyes” emerged from the ship, merged into one, creating a “single object” that was accompanied by a loud buzzing sound. After that, “the spherical object flashed with a blindingly bright light.”
According to the report, 23 soldiers were “turned into pillars of stone” and two survived because they were in a shadowed area and were not exposed to the full impact of the flash. It is also noted that the remains of “petrified soldiers” and the wreckage of the ship were allegedly transported to a secret research base near Moscow. There they discovered that the molecular structure of the bodies coincided with limestone. The document also states that scientists attribute this to an “energy source” that is currently unknown to mankind.
