The Pentagon has received hundreds of reports of new UFO sightings, including “several particularly interesting cases,” according to the director of the office that investigates these reports, but reiterated it found no evidence of alien activity.

The Pentagon’s UFO office has received more than 700 reports, a newly declassified assessment reveals. It’s a dramatic increase in witness sightings and accounts that adds to a growing list and comes as former Defense Department officials claim the U.

A former Pentagon official testified to Congress that the U.S. government has evidence that "we are not alone in the cosmos," but that a "cabal" of officials is hiding the information.
