Schoolchildren across the US are walking out of school on Friday to demonstrate against gun violence.
The National School Walkout marks the 19th anniversary of the Columbine High School massacre in Colorado.
Connecticut high school pupil Lane Murdock set up the event in the wake of the Parkland shooting in Florida.
Students are leaving schools at 10:00 across America’s time zones. Schoolchildren in every state are expected to participate.
The goal of the demonstration, which involves more than 2,000 schools, is to raise awareness of gun violence and to combat political inaction.
