Canadian police say a suspect is in custody after at least four people – two of them police officers – were killed in a shooting in the eastern city of Fredericton, New Brunswick.
The city police confirmed the officers’ deaths on Twitter.
The pair have not been named, and the circumstances around the incident remain unclear.
Police have ended a lockdown in the area but continue their investigation.
A local TV reporter said he had heard four gunshots just after 07:00 (11:00 GMT).
Nick Moore, a journalist from CTV Atlantic, posted video footage of the scene on Twitter, showing emergency vehicles outside a house.
