In the wake of a deadly shooting at Perry High School, Iowa students are planning to walk out of class Monday and march to the state Capitol to protest what they say is lawmakers’ inaction on gun violence.

The call for students to participate was put out by March For Our Lives Iowa just hours after authorities said a Perry High School student shot and killed sixth-grader, and injured seven others at the school on Thursday. The group began organizing the walkout after students repeatedly voiced their frustration over the school shooting.

“The shooting has hit really close to home for a lot of us,” Akshara Eswar, one of the group’s executive state directors, told the Des Moines Register, part of the USA TODAY Network. “People are angry. They’re thinking about it constantly.”
