The US Defence Department on Friday released a second batch of previously classified documents on ​alleged UFO sightings, including references to ‌people reporting unexplained green orbs, discs and fireballs.

At the order of President Donald Trump, the first batch ​was made public on May 8. ​He is the latest president to release ⁠US government reports on unidentified flying ​objects, a disclosure process that began in the ​late 1970s.

Defence Secretary Pete Hegseth said the documents, photos and videos of what are officially known as “unidentified ​anomalous phenomena” had long fueled speculation.

“It’s ​time the American people see it for themselves,” he ‌said ⁠in a statement.

One of the 222 files released on Friday contains 116 pages of documentation relating to a series of reported ​sightings and investigations ​in ⁠a top-secret facility in Sandia, New Mexico, from 1948 to ​1950.

“This file contains 209 sightings of ‘green ​orbs’, ‘discs’, ⁠and ‘fireballs’ reported near the military base,” the Defence Department said.

Experts said the first batch ⁠contained new ​videos of known sightings ​but gave no conclusive evidence of alien technology or ​extraterrestrial life.
