The Pentagon has shot down another unidentified high-altitude object over Lake Hurhn, which is located between the United States and Canada.
This was reported by CNN, citing military and Congressional sources.
The object was shot down by Air Force and National Guard pilots on the US-Canadian border.
The American authorities have declined to say whether it resembles the first Chinese spy balloon or two other smaller cylindrical 'UFOs' neutralized in Alaska and Canada.
After the first episode, the US security forces are on high alert.
