QUEBEC CITY — The French Canadian university student charged with killing six Muslim men during evening prayers at a mosque was known for far-right, nationalist views and his support of the French rightist party led by Marine Le Pen.

Alexandre Bissonnette was charged Monday with six counts of first-degree murder and five counts of attempted murder over the shooting rampage at a Quebec City mosque that Canada’s prime minister called an act of terrorism against Muslims.

Bissonnette made a brief court appearance and did not enter a plea in the attack staged during evening prayers Sunday. Wearing a white prisoner jump suit, his hands and feet shackled, he stared down at the floor and fidgeted, but did not speak.

The 27-year-old suspect, who has espoused support for Le Pen and U.S. President Donald Trump on his Facebook page, was known to those who monitor extremist groups in Quebec, said François Deschamps, an official with a refugee advocacy group.

“It’s with pain and anger that we learn the identity of terrorist Alexandre Bissonnette, unfortunately known to many activists in Quebec for taking nationalist, pro-Le Pen and anti-feminist positions at Laval University and on social media,” Deschamps wrote on the Facebook page of the group, Bienvenues aux Refugiés, or Welcome to Refugees.

An anthropology and political science major at Laval University in Quebec City, Bissonnette had also expressed support on his Facebook profile for “Génération Nationale,” a group whose manifesto includes the rejection of “multiculturalism.”

Authorities said Bissonnette was unknown to police.

The grandson of a decorated World War II veteran, Bissonnette appears in a Facebook photo as a boy dressed as an army cadet, a military leadership program for Canadian youths. But cadets are not members of the Canadian Armed Forces and do not receive military training.

For Le Pen and her supporters, “massive migration” is supplanting French civilization and is at the root of many France’s modern woes.
