Students from Parkland, Florida visited fellow high-schoolers from Pittsburgh, Pennsylvania to share words of support and encouragement as witnesses to violent tragedies.

Students from Taylor Allderdice High School in Pittsburgh were among hundreds of others to take a stand against violence this week.

They were joined Friday by students from Marjory Stoneman Douglas High School in Parkland, Florida, where 17 people were killed last year during a mass shooting.

Friday's visit was part of an entire weekend of events organized by the Jewish Community Center of greater Pittsburgh.

All the students gathered in the library and shared stories with the goal of helping one another better understand gun laws and their power as citizens.

"We want to spread the message of hope and unity and overcoming tragedy because it's so hard to do that alone," said Lizzie Eaton, a Parkland student. "That's why we wanted to come together with our community and the Tree of Life community and really share what we experienced as our two communities and come together."

After the high school event, the Parkland students traveled to the Tree of Life Synagogue to pay their respects to the 11 people who were killed and seven injured in an October mass shooting there.
