At least six people were killed and eight injured after gunmen opened fire on worshipers at a mosque in Quebec City, Canada, during evening prayers on Sunday. The police told AP that they have arrested two suspects, and identifed them as Alexandre Bissonnette and Mohamed el Khadir.

The Quebec Police in a tweet said that all occupants had been evacuated, and the situation was under control. Eyewitnesses told The Guardian that around 40 people were present at the mosque when three armed men barged in and began to shoot.

Canadian President Justin Trudeau expressed his condolences. “Canadians grieve for those killed in a cowardly attack on a mosque in Quebec City. My thoughts are with victims & their families,” he tweeted. Public Safety Minister Ralph Goodale said that he was “deeply saddened” by the deaths.

In a statement, Trudeau said: “We condemn this terrorist attack on Muslims in a centre of worship and refuge...Muslim-Canadians are an important part of our national fabric, and these senseless acts have no place in our communities, cities and country.”
