Across the United States, many students walked out of school Wednesday to say enough is enough with regards to gun violence.

The national school walkout started at 10 a.m. in each time zone and was scheduled to last for at least 17 minutes — one minute for each person killed in a school shooting that happened exactly one month ago in Parkland, Florida.

More than 2,500 walkouts were planned across the country, according to Empower, the youth branch of the Women’s March that has been organizing the event.

Participants called for stricter gun laws as they also remembered the people who lost their lives in Parkland.

Many schools accommodated the demonstration. Others didn’t allow it, encouraging students to express themselves in ways other than walking out.
