Scenes from March for Our Lives rallies around the world

Students, teachers, parents and their allies converge on the nation’s capital and cities around the world Saturday to rally for gun control and school safety measures in the wake of last month’s shooting in a Florida high school.

Hundreds of thousands of people from across the globe participate in 800 marches in solidarity with the March for Our Lives, organized by students of Marjory Stoneman Douglas High School in Parkland, Fla., where a gunman killed 17 people and injured others on Valentine’s Day. The accused shooter, 19-year-old Nikolas Cruz, was a former student at the school and was armed with an AR-15-style rifle he had legally purchased a year ago, authorities said. (GMA)
