To mark the two-year anniversary of the deadly 2016 shootings at the Pulse Nightclub in Orlando, Florida, a group of student activists organized a National Die-In. 。

At 12 p.m. ET on Tuesday, high school students from across the country gathered on the lawn of the U.S. Capitol Building in Washington, D.C.. There they dropped to the ground for 12 minutes, or 720 seconds, in protest of gun violence.。

According to the organizers, the time represents "the approximate number of people who have died in mass shootings" since 49 people were killed in the Pulse Nightclub tragedy. 。
