WASHINGTON (AP) — The White House is defending the shootdowns of three unidentified objects in as many days even as it acknowledged that it had no indication they were intended for surveillance in the same manner as the high-altitude Chinese balloon that traversed American airspace earlier this month. White House national security spokesman John Kirby says the three objects, including one shot down Sunday over Lake Huron, were traveling at such a low-altitude as to pose a risk to civilian air traffic, And though the Biden administration does not yet have evidence that they were equipped for spying purposes, or even belonged to China, officials also couldn’t rule it out either, he said.
