BOISE, Idaho (AP) -

An anti-abortion organization says Boise State University is violating free speech laws by limiting students' protest to just a handful of areas on campus.

Abolitionists4Life filed the lawsuit against the university Friday. They argue that BSU is violating their First Amendment rights.

The group says the university required them to put up warning signs during a May protest because officials considered their material controversial.

Currently, the university has six speech zones designated as protest areas on its campus. Students must reserve the space in advance, put up warning signs if the university determines the protest may be offensive and cannot distribute fliers outside of their reserved zone.
