Nazi flags were hung on the side of a Texas school, outraging local officials and sparking calls for the perpetrators to be held responsible.

Students on Saturday spotted the flags displayed on the east side of the Rockwall-Heath High School, Mayor Jeremiah McClure and the Heath Department of Public Safety announced on social media on Sunday, and officials immediately removed the “antisemitic materials.”

McClure and the Heath DPS didn’t detail the exact nature of the antisemitic flags and didn’t immediately respond to Jerusalem Post inquiries, but the Dallas-based WFAA Channel 8 reported that residents confirmed that the flags contained Nazi symbols.

Acts of hatred at the Rockwall-Heath High School

“I stand with our community in firm opposition to any acts of hatred, including the hateful display of flags that were found at Rockwall-Heath High School yesterday morning,” McClure said on Facebook. “We believe in the power of love, unity, and respect for all people, as God calls us to do.”

The Heath DPS said it took the incident seriously and was committed to “holding those responsible accountable.”
