CNN)Thousands of students across the United States walked out of class Wednesday to demand stricter gun laws in a historic show of political solidarity that was part tribute and part protest.

From Maine to California, the 17-minute walkout began around 10 a.m. in each time zone -- one minute for each of the 17 people killed at Florida's Marjory Stoneman Douglas High School one month ago. Students across the globe also left their classrooms Wednesday in solidarity with the American students' movement.
