A lone gunman wearing a bulletproof vest opened fire in an apartment and a hospital in the Dutch port city of Rotterdam on Thursday, killing three people, including a 14-year-old girl, police said.
The shooting sent patients and medics fleeing the Erasmus Medical Center in downtown Rotterdam, including some who were wheeled out of the building in beds. Others barricaded themselves into rooms and stuck hand-written signs to windows to show their location.
