IOWA CITY, Iowa (AP) — Dozens of high school students left their Iowa City classrooms, Monday, to send a message: School shootings must stop. Students from at least three schools — City High, West High and South East Junior High — walked Monday to a gathering spot in downtown Iowa City. By 11:45 a.m., an estimated 200 students were chanting in front of the Old Capitol building. Some carried signs decrying gun violence.

Speaking through a megaphone, a student speaker read the names of the 17 victims of last week’s Parkland, Florida, shooting. The other students repeated the names in unison.
