Colombia said an "object" had overflown its territory after Washington warned that a suspected Chinese spy balloon similar to the one shot down off the US coast had been spotted over Latin America.
Colombia's Air Force said the object with "characteristics similar to those of a balloon" was detected on Friday and "monitored until it left the national air space."
The object flew at an altitude of 55,000 feet (17,000 meters) and an average speed of 25 knots (29 miles per hour, 46 kilometers per hour), said an air force statement Saturday, adding it "did not constitute a threat to national security and defense or to aviation security."
The air force said it was conducting investigations in coordination with other countries and institutions "to establish the origins of the object."
A US fighter jet on Saturday shot down what it said was a Chinese spy balloon off the coast of South Carolina, denouncing an "unacceptable violation."
The craft spent several days flying over North America, ratcheting up tensions between Washington and Beijing, which said it was a weather balloon blown off course.
Another suspected Chinese spy balloon was seen over Latin America, the Pentagon said Friday, without providing details.
No other Latin American country has reported spotting the craft, while Venezuela on Sunday lashed out against "the attack by the United States against a civilian unmanned aircraft of Chinese origin."
Caracas, under US sanctions, said in a statement: "The United States once again resorts to the use of force rather than treating this situation with the seriousness and responsibility it merits."
