Mississippi will inaugurate a marker Tuesday recalling a civil rights protest 50 years ago when a white mob attacked a racially mixed group seated at a whites-only lunch counter.

On May 28, 1963, the mob attacked some Tougaloo College students and faculty members who opposed segregation by sitting at the whites-only counter at a Woolworth's five-and-dime store in Jackson. Some of the peaceful demonstrators were beaten. Others were doused with ketchup, mustard and sugar.

The marker is part of the Mississippi Freedom Trail, a series of signs honoring those who challenged segregation. The sit-in was similar to other protests around the South and occurred two weeks before Mississippi NAACP leader Medgar Evers was assassinated in Jackson.

The Woolworth's, which was located on a downtown Jackson street, closed decades ago.
