US defends decision to shoot down 3 unidentified objectsWASHINGTON (AP) — The White House on Monday defended the shootdowns of three unidentified objects in as many days even as it acknowledged that officials had no indication the objects were intended for surveillance in the same manner as the high-altitude Chinese balloon that traversed American airspace earlier this month. The weeks-long succession of objects, starting with a giant white orb first detected over U.S. skies in late January, has puzzled American officials and stirred curiosity around the world. Kirby spoke from the White House podium hours after China alleged that more than 10 U.S. high-altitude balloons have flown in its airspace during the past year without its permission. The latest of the three objects was shot down Sunday over Lake Huron after being detected a day earlier over Montana. None of the three most recent objects has been recovered, Defense Secretary Lloyd Austin told reporters in Brussels, where he was scheduled to attend a NATO defense ministers meeting this week.
