The US has shot down another unidentified object that it says flew near sensitive military sites and could have been used for spying.
It was downed over Lake Huron in Michigan at 2.42pm local time on Sunday on President Joe Biden’s orders.
A US F-16 jet fired a missile at about 20,000ft amid concerns that its altitude and flightpath could endanger civilian planes.
It is the fourth incident in just over a week – and the third in as many days – after objects were shot down in Alaska and Canada on Friday and Saturday,
A senior US official, speaking anonymously, described the latest object as having “an octagonal structure with strings hanging off but no discernible payload”.
