"It's a very, very difficult time," Elsa Ray told CBC News on Saturday. She represents Collective Against Islamaphobia in France. "And I am also afraid of the consequences on Muslims in France."
In the worst assault on France's homeland security for decades, 17 victims lost their lives in three days of violence that began with an attack on the Charlie Hebdo weekly on Wednesday and ended with Friday's dual sieges at a print works outside Paris and a kosher supermarket in the city.
The whereabouts of the partner of the Jewish deli attacker, 26-year-old Hayat Boumeddiene, remains unknown. Police listed her as a suspect in that strike and an earlier killing of a policewoman, describing her as "armed and dangerous."
"We are shocked and sad about what happened," said Ray. "There has already been a lot of backlash against Muslims...We have had many mosques attacked, one of them with a bomb."
Ray said there is also "a lot of physical and verbal abuse" against Muslims in France as well as "hate speech over the internet."
Ray implored all people to be "open-minded and to try to communicate with each other."
On Saturday, tens of thousands flocked to local vigils, with 80,000 in Toulouse and 30,000 in the Riviera city of Nice, and a similar number in Pau in the southwest.
"It's no longer like before," said Maria Pinto, on a street in central Paris. "You work a whole life through and because of these madmen, you leave your house to go shopping, go to work, and you don't know if you'll come home."
Anand Memon, an expert on French politics and European integration at King's College London, told CBC News that France was already divided prior to the attacks.
"The far right National Party was polling well into 20 per cent even before this," he pointed out in an interview on Saturday. "They have proposed a referendum on bringing back the death penalty [and] I think it will resonate with a lot of working-class voters who are frustrated at what they see as a weak response to Muslim extremism.
"There has...always been tensions in French society. Many members of the Muslim community are part of the underclass who live in the suburbs of the big cities. There is real disillusionment among Muslim youth."
Sunday 'silent march'
