A second China UFO sighting has residents on edge, just seven days after an unidentified flying object shut down a Chinese airport.

The new UFO sighting took place in Chongqing in eastern China on July 15. Witnesses told Shanghai Daily they saw the same thing: "four lantern-like objects forming a diamond shape that hovered over the city's Shaping Park for over an hour."

Like the one before it, there has been no official explanation to date for this latest incident.
