At least four people - including two police officers - were killed and a suspect is in custody after a shooting in a Canadian city.
The suspect is currently being treated for serious injuries in hospital.
The two officers shot and killed have been named as Lawrence Robert Costello, 45 and Sara Mae Helen Burns, 43.
Police warned residents in a neighbourhood in Fredericton, New Brunswick, to stay at home and lock their doors during the incident.
Others were told to "avoid" the scene.
Journalists covering the shooting reported hearing what sounded like four gunshots after officers had arrived and sealed off the area.
