A blimp reportedly caught fire and crashed near Erin Hills Golf Course in Erin, Wisconsin, during the first round of the U.S. Open on Thursday.
In a statement, The United States Golf Association (USGA) said the blimp was unaffiliated with the tournament and that the pilot was injured.
"Our thoughts and prayers are with those who were injured," the USGA said.
Multiple videos and photos were posted on social media shortly after 11 a.m. CDT that showed the blimp deflated and in flames. One spectator reported that they saw people parachute out of the blimp before it crashed.

The Milwaukee Journal Sentinel reported that rescue crews had arrived on the scene shortly after the blimp crashed around 11:20 a.m. near Highway 83 and Highway 167.
"There were no thunderstorms in the area at the time of the incident," said AccuWeather Senior Meteorologist Alex Sosnowski. "In fact, skies were partly sunny and winds were light at ground level, mainly from the west at 5-10 mph. A few hundred feet above the ground, winds were probably from the west between 8 and 14 mph."
The blimp was reportedly operated by AirSign and was featuring a promotion for Pentagon Federal Credit Union.
