WASHINGTON (AP) — Phylicia Rashad is best known for starring roles on stage and television, but as a director she decided to commemorate a historic moment that helped spur the civil rights movement.

The Tony Award-winning actress directed a reading of the play “Four Little Girls: Birmingham 1963” at the Kennedy Center Sunday to mark the 50th anniversary of the bombing at 16th Street Baptist Church in Birmingham, Ala. Four girls were killed in the explosion, which was set by white supremacists and helped spur passage of landmark civil rights legislation.
