Groups of opposing protesters clashed outside a school board meeting in Glendale Unified School District near Los Angeles Tuesday night over a resolution the board was considering that would expand LGBT curriculum offerings in the district.

Video of the outside of the building where the meeting took place showed protesters supporting the resolution brawling with protesters who opposed it. The fights resulted in arrests, according to KTLA.

The brawl reportedly prompted local police to declare an unlawful assembly and order the crowds to disperse. A barrier between the opposing groups was eventually erected, as well. The crowd size was an estimated 200 people, according to CBS News.

The resolution at the heart of the contentious protest was a reauthorization of the district's LGBT studies curriculum, which varies per grade level, according to the school district.

The school district issued a statement on Facebook on Monday claiming to "clarify and correct ... disinformation" about the resolution.

"Recently, intentional and harmful disinformation has been circulating about what is being taught in our district and the ways we serve our students," the district's post said. "This includes disinformation about LGBTQIA+ curriculum, sex education, and supporting transgender and gender non-conforming youth."

In a statement to CBS News, the school district said it was "committed to providing a safe, inclusive environment where every child can learn and thrive."

"We know that kids do better when their parents are involved in their education," the district said. "We work with parents as partners and encourage all parents and other caregivers to be inquisitive and engaged with what is going on in our school community. Let's continue to work together, commit to having difficult conversations, ask questions, and maintain a civil discourse for the benefit of all students."
