ON GUARD

U.S. marshalls fanned out to several Southern cities to guard abortion clinics after a doctor and an escort were killed, and the doctor's wife wounded, at a clinic in Pensacola, Fla. on Friday. U.S. Attorney General Janet Reno assigned the forces to many facilities including ones in Melbourne, Fla., Fargo, N.D., Falls Church, Va., and Wichita, Kan.
