The US has shot down a suspected Chinese spy balloon that has been flying over its airspace.
Television footage showed a small explosion, followed by the balloon descending toward the water off the Carolina coast.
The balloon was shot down by an F-22 fighter aircraft, about six nautical miles off the coast near Myrtle Beach, South Carolina, Pentagon officials said.
Ships were deployed in the water to mount the recovery operation.
US President Joe Biden said he wanted the balloon brought down on Wednesday but was advised that the best time for the operation would be when it was over water.
“They successfully took it down and I want to complement our aviators who did it,” Mr Biden said.
A US defence official said the aircraft was a spy balloon and that China intended to use it on sensitive military sites.

How did the US bring down the ‘spy balloon’?
The balloon was shot down at 2:39pm local time by a military fighter jet from Langley in Virginia.
The fighter jet shot a single missile into the balloon, which caused it to crash into the ocean.
“This was the first opportunity to successfully bring down the balloon without posing a threat to civilians”, a senior US official said.
Officials said they were “confident” the balloon was “seeking to monitor sensitive sights” and they will “seek to recover it”.
The balloon was flying between 60,000 to 65,000ft.
The debris was spread out over seven miles, US officials said.
Mr Biden had warned the US was “going to take care of” the craft after it was spotted again on Saturday – this time over North Carolina.
The US had previously hesitated to shoot the balloon because of the risks to people on the ground from falling debris.
Ahead of the operation, flights were halted at three airports including Myrtle Beach International Airport in South Carolina because of a “national security effort”, the Federal Aviation Administration (FAA) said.
The discovery of the balloon has stirred tensions and a diplomatic row between China and the US.
However, China insisted the balloon was used for meteorological and other scientific research and had been blown off course.
The object is believed to have flown over the Aleutian Islands, off the coast of Alaska, and through Canada before entering the US earlier this week.
