The White House answered several questions on Monday pertaining to the recent shooting down of three unidentified aerial objects over the past week.

White House spokesperson Karine Jean-Pierre made it clear that there was no connection whatsoever to extraterrestrial activity with the last three aerial objects - the first being a Chinese weather balloon that was suspected of being a spying device.

"I just wanted to make sure we address this from the White House," Jean-Pierre said on Monday. "There have been questions and concerns about this but there is no -- again, no -- indication of aliens or extraterrestrial activity."

But the nature of the last three aerial objects remains unknown.

The first was confirmed by the Pentagon as being part of an ongoing, global "fleet" of Chinese espionage balloons, but China rejected the accusations and rectified it was a weather balloon that strayed off its normal course.

Chinese Foreign Ministry spokesperson Wang Wenbin said on Monday that high-altitude balloons originating from the US have flown over Chinese airspace more than 10 times since January last year.

White House National Security Council spokesperson John Kirby told reporters the US is "not flying surveillance balloons over China."

"I'm not aware of any other craft that we're flying over into Chinese airspace," he said.
