Five people are in critical condition at a Quebec hospital this morning from a shooting at a mosque that killed six and injured eight others, according to hospital officials.
Police had said two suspects were in custody, but the Royal Canadian Mounted Police said later today that only one person detained is considered to be a suspect, and the second individual is now considered to be a witness.
The motive is not clear and police say the investigation is ongoing.
One witness to the shooting told ABC News that gunmen shouted "Allahu Akbar" -- God is great -- and opened fire. The witness said he was inside the mosque when he saw three suspects walk in; he said the gunmen sounded like they had regional accents from Quebec.
Other witnesses have said they saw two suspects.
The mosque shooting comes two days after President Donald Trump's Friday travel ban affecting people from seven predominately Muslim countries, and one day after Canadian Prime Minister Justin Trudeau tweeted on Saturday, "To those fleeing persecution, terror & war, Canadians will welcome you, regardless of your faith."
Trudeau called the mosque shooting a "terrorist attack on Muslims."
"While authorities are still investigating and details continue to be confirmed, it is heart-wrenching to see such senseless violence. Diversity is our strength, and religious tolerance is a value that we, as Canadians, hold dear," Trudeau said in a statement. "Muslim-Canadians are an important part of our national fabric, and these senseless acts have no place in our communities, cities and country."
Trump called Trudeau this morning to express his condolences and offer assistance, according to Trudeau’s office.
Philippe Couillard, premier of Quebec, who also called the shooting terrorism, vowed to stand with Muslims in the community, adding that Quebec should not withdraw as a result of such violence and become a closed society because of the shooting, and should instead continue to welcome everyone.
The Quebec police said this morning that all local mosques have increased security.
