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.

Pentagon officials say there have been more than 20 UFO sightings in a 12-month period that need further analysis. While the majority of reports were explained away by everyday objects, some have left officials stumped. But don't get too excited - this doesn't mean an alien invasion is close by.
