The source said that the attacker fled the scene in front of the Henry Dunant Hospital, in the 16th district of the French capital, using a two-wheeled vehicle.
The geriatric hospital, located in an affluent neighborhood, is run by the French Red Cross and currently serves as a Covid-19 vaccination center.
Speaking to BFM TV, 16th District Mayor Francis Szpiner said the shooting “was not a terrorist attack on a vaccination center” and that vaccines will continue at the site.
“At this time, the attacker has not been identified. It goes without saying that his identification will allow a significant advance in the investigation. We are leaning towards a targeted criminal attack.”
The Paris prosecution told CNN that it has launched an investigation into a murder and an attempted murder following the shooting.
The investigation will be handled by the criminal investigation unit, the prosecutor’s office said.
Officials from the 16th district city hall said the victim who died was a man, but they did not identify him further.
The second victim, a security guard, remains in a “life-threatening” condition, according to a city council tweet.
