More than fifty anti-Muslim attacks were recorded in France since the jihadist attack against Charlie Hebdo on Wednesday, announced the Observatory against Islamophobia of the French Council of the Muslim Faith (CFCM), which calls on the state “to strengthen the monitoring” of mosques.
According to the president of the observatory Abdallah Zekri, citing figures from the Ministry of the Interior, 21 violent acts (shots, grenades launched …) and 33 threats (letters, insults, etc.) have been recorded since Wednesday. This count is still incomplete, said the Muslim leader, who said he was “outraged” by the numbers “unheard of” in less than a week.
This information follows the publication on Twitter of a map with 14 incidents that took place in mosques in France since Wednesday.
