PARIS—Paris police are hunting for a gunman who opened fire Monday near a hospital in the wealthy 16th district of the French capital, killing one person and injuring another. Witnesses at the scene suggest it could be a case of tragic score-settling, while authorities have not made any links with terrorism. Paris police, who opened a murder inquiry Monday, said the shooter fired several shots before fleeing on a two-wheeled vehicle. Police had no other immediate details. Noura Berrahmouni, DSPAP Alliance, said the injured person, a woman, was a security agent for the hospital. “It was so fast we suppose it was a score settling … If not, we think there would be more victims,” she said. The shooter wore a hood, and fired several times, according to witnesses on BFM-TV. By Jeffrey Schaeffer
