After Havre airspace in Montana was shut down for nearly an hour on Saturday, after a mystery object was seen flying in the skies, local maritime authorities in East China’s Shandong Province reported on Sunday that they had spotted a UFO over the waters near the coastal city of Rizhao.

They also said that the Chinese military was prepared to shoot down the unidentified flying object. Fishermen in the area were warned to steer clear of the waters near the port city of Qingdao. They did not say what the object was. No other details about the incident were immediately available.

Just hours before on Saturday, Canadian Prime Minister Justin Trudeau, revealed that “an unidentified object” that violated Canadian airspace had been shot down by U.S. F-22s in Yukon by US and Canadian forces. It was a joint order given by Trudeau and President Joe Biden, the White House revealed later.

Soon after the incident, US and Canadian aircraft were quickly scrambled on Saturday night to Havre. According to The North American Aerospace Defense Command, fighter jets were unable to find the mystery object above Havre. The Command Center also reported that they “did not identify any object to correlate to the radar hits.”

They will continue to monitor the situation following three incidents that already occurred in the past week. Two Chinese spy balloons have been shot down over the US and a third object over Canada.
