President Donald Trump blamed mass migration and Islam for unrest in France on Tuesday as students continued demonstrations outside schools over deteriorating educational conditions.

"What's happening in France is nothing less than out-of-control mass migration. This isn't about schools, this is about Islam wanting to take over a once great Country!" Trump wrote on Truth Social. He did not provide additional details or evidence for the claim.

The demonstrations began in the Paris region in mid-September before spreading to cities and towns across France. Students have primarily cited problems within the education system, including teacher shortages, deteriorating classrooms, long school days and unequal resources between schools in wealthier and disadvantaged communities.

Protests continued Tuesday at Hélène Boucher High School in Paris' 20th arrondissement, where students used trash cans and bicycles to create a makeshift barricade outside the building. Parents and other adults stood between the protesters and police officers monitoring the demonstration.

The school was among hundreds closed as French authorities responded to escalating unrest. Officials began closing schools last week following widespread property damage and injuries involving students, school employees and police.

More than 400 schools were closed Friday after demonstrations involving thousands of students became violent. Some protesters clashed with police and set fire to schools and vehicles, prompting a heavier security response.

French media reported additional demonstrations Tuesday morning in multiple cities. Labor unions also called for workers to join protests later in the day, increasing pressure on President Emmanuel Macron's government.

Police made more than 5,000 arrests during the previous week's unrest, with minors accounting for approximately 85% of those detained. The use of tear gas and other riot-control weapons against teenage protesters has further angered some parents and teachers.

Students have pointed to basic problems inside schools, including classrooms without enough desks and chairs, excessive heat in buildings without air conditioning and rat infestations. They have also complained about teacher shortages, heavy workloads and disparities in educational opportunities.

French high school students also face some of the longest compulsory school hours in Europe. Demonstrators argue that students in poorer areas are not receiving the resources and opportunities promised under France's national motto of "Liberty, Equality, Fraternity."

The protests have largely centered on education and government resources, while Trump characterized the broader unrest as evidence of problems associated with mass migration and Islam. His comments come as Macron's government faces mounting pressure to address both the immediate disruption at schools and the wider grievances fueling the demonstrations.
