Hundreds of students walked out of their classes and took off down the highway Tuesday, headed toward the high school in Parkland, Florida, where 17 people were slain last Wednesday in a deadly mass shooting.

School buses then went and picked them up for the return journey back to their own school.

The Hill reported:

The students from West Boca Raton High School walked out of class and are marching toward Marjory Stoneman Douglas High School in Parkland, Fla., where a gunman killed 17 people, the Miami Herald reported.

Authorities from Palm Beach and Broward counties are following the students to make sure they are safe, a spokesman told the Miami Herald.

West Boca Raton High School is about seven miles from Marjory Stoneman Douglas High School.

The walkout is an attempt to show solidarity with the students who survived the massacre and is a call to action, CBS News reported.

High school students in Fort Lauderdale and Hollywood, Fla., also walked out on Tuesday, and students in Hialeah, Fla., are planning a walkout Wednesday, according to the Herald.
