Six people were killed in a shooting at a Quebec City mosque during evening prayers in an attack Canada’s Prime Minister called a “terrorist attack on Muslims”.
Earlier, police said they had arrested two men, including one who called 911 to say he was armed but ready to give himself up, but later said just one remains a suspect.
More than 50 people were at the Quebec Islamic Cultural Centre when the shooting erupted on Sunday night.
Along with the six killed, five people were in critical condition and 12 others suffered minor injuries, University of Quebec Hospital Centre spokeswoman Genevieve Dupuis said on Monday.
The age of those killed ranged from 35 to 65.
Alexandre Bissonnette and Mohamed el Khadir were identified as suspects by Quebec City court clerk Isabelle Ferland, however authorities later charged Bissonnette with six counts of first-degree murder and clarified that Mr Khadir was just a witness.
Bissonnette has also been charged with five counts of attempted murder.
