Spy

China threatened to take "countermeasures" against United States entities over the takedown of their spy balloon earlier this month.

South Carolina, Alaska, Canada, and Michigan's Lake Huron each reported unidentified objects flying overhead.

A part of Montana airspace was temporarily closed due to a “radar anomaly,” then later reopened, after an unidentified object was shot down over Canada, the Federal Aviation Administration (FAA) said.

The Pentagon issued a statement Saturday revealing details about how an unidentified object was shot down by the U.S. military over Canada.

The U.S. shot down a fourth flying object Sunday afternoon at 20,000 feet above Michigan’s Lake Huron, the Pentagon said, underscoring its stepped-up defense of North American airspace following the discovery of a suspected Chinese spy balloon.

The U.S. military on Friday shot down an "object" flying in territorial waters over Alaska less than a week after an F-22 fighter jet shot down a Chinese spy balloon over the Atlantic.

Despite reaching out to Chinese Defense Minister Wei Fenghe through a special crisis line, the Chinese official declined the call, leaving Austin's efforts unanswered.

United States officials believe the Chinese balloon was affiliated with a military-aerial surveillance program that monitored at least 40 countries.

The US House of Representatives is expected to pass a resolution blaming China for a "brazen violation of United States sovereignty" and accusing it of trying to "deceive the international community through false claims about its intelligence collection campaigns."

The US Navy has recovered and is investigating the remains of a suspected Chinese surveillance balloon shot down off the coast of South Carolina.
