Two people have been shot, including one fatally, outside a hospital in Paris.
The incident happened at the Henry Dunant private hospital, owned by the Red Cross, in the upmarket 16th arrondissement at 1.45pm local time.
French police said the attacker fled the scene on a motorcycle, and they were not treating the incident as terror-related.

"It is not a terrorist attack, it was probably a case of score-settling," Francis Szpiner, mayor of the 16th arrondissement, told reporters.
Police officers have set up a large cordon around the scene on Rue Michel Ange.
The Paris prosecutor has opened a murder investigation, a spokesman said.
Eyewitnesses said the attacker fired several shots at point blank range at the deceased man as he lay on the ground.
Police union official Rocco Contento told BFM television there had been an argument between the gunman and a woman, who has been identified as a security official at the hospital, and that a man who tried to intervene was then shot.
The owner of a neighbouring restaurant told the station: "I saw a man in a black parka open fire and another man fall to the ground. He shot him twice in the head. Then he calmly walked off and a moped was waiting for him several hundred metres away."
