Authorities say a gunman entered a Pennsylvania hospital’s intensive care unit and took staff members hostage before he was killed by police.

Authorities described the shooting of a gunman who opened fire at a Pennsylvania hospital as “absolutely justified, beyond any and all doubt.”

YORK, Pa. (AP) — Workers at a Pennsylvania hospital who were injured during a shooting that left the gunman and a police officer dead were reported “medically stable” Sunday as the hospital remained closed to visitors, according to the hospital.
