Greta Thunberg says French students are being “robbed” amid nationwide prot

Climate activist Greta Thunberg has joined high school students in France protesting against the government's pension reform plans.

The 20-year-old Swedish activist joined students in the southern city of Montpellier, saying they were being 'robbed' of their future.

The protests, which began last week, have seen students and teachers clash with police, with hundreds arrested.

The French government has proposed raising the retirement age from 62 to 64, a move that has sparked widespread anger.

Greta Thunberg's involvement in the protests is likely to draw further international attention to the issue.
