A peaceful demonstration and a moment of silence turned chaotic Tuesday after Confederate flags turned up at a rally against gun violence at a Haslet high school.

A student-led event began inside and then moved outside Eaton High School, where about 100 students had gathered to remember those killed in the shootings at Florida's Marjory Stoneman Douglas High School, the Fort Worth Star-Telegram reported.

A student organizer said that all changed once others showed up with Confederate flags.

"People came with the intention to disrupt," organizer Jordan Vine told the Star-Telegram.

Vine video shared shows her stepping on a Confederate flag and saying: "We don't stand for this here."

No one was hurt or arrested at the event, a Fort Worth police spokesman said.

The event began peacefully with students discussing all sides of the gun debate, Vine told the Star-Telegram, but it changed when the discussion moved outside and several students pulled out Confederate and "Don't Tread On Me" flags.

Northwest ISD said it's looking into the matter.

"Approximately 100 students participated," a district statement read. "During the event, differences of opinions were expressed. Administration at the campus is addressing any concerns students have as well as any disciplinary issues."
