On March 14, students across the US and internationally staged a walkout in remembrance of the victims of the school shooting in Parkland, Florida, one month previously.

At 10 am local time in each US location, students walked out of their classrooms and stood in silence for 17 minutes in honor of the 17 people who lost their lives at Marjory Stoneman Douglas High School on February 14. The walkout was organized by Women’s March Youth Empower. Credit: Sandy Spring Friends School via Storyful
