High school student Kamil Alahyan, 18, said: "I'm here for so many reasons – the elections coming up in 2027, politicians who lie, the ultra-rich who've been taking more and more wealth over the past 10 years."
Ryad Rani, the head of the LSU high school student representative body, told journalists in Paris: "The government is trembling and it's right to tremble because when the French people are angry, they never let up."
