Several boats sank in a lake in the US state of Texas during a parade to support President Donald Trump in the November election, officials say.
Authorities say the unstable water was most likely caused by a large number of boats moving near Lake Travis, near the state capital, Austin.
The images showed boats with Trump campaign flags maneuvering nearby.
The media reported that people had to be rescued from the water, but there were no immediate reports of injuries.
The event, called Lake Travis Trump Boat Parade, was hosted on Facebook and more than 2,600 people noted that they participated in it.
An investigation has been launched and there is no evidence of any intentional act, said Kristen Dark, a spokeswoman for the Travis County Sheriff’s Office.
“We have responded to many calls from ships in danger, many of them have sunk,” he said. “We had a tremendous number of boats on the lake today … When they started moving at the same time, it caused significant waves.”
The incident happened around 12:00 (17:00 GMT) on Saturday, the Labor Day weekend in the USA. The event page reported that ships were called to drive at 10 mph (16 km / h).
Paul Yura, of the National Weather Service in Austin / San Antonio, told the Associated Press that there were no storms in the area at the time of the parade.
