Claim: Greta Thunberg joined student protests in France, according to Al Jazeera.
What we found: Greta Thunberg was reported to have arrived at Paul Eluard high school in Saint-Denis, a suburb of Paris, where student protests were taking place. Al Jazeera provides this information indicating Thunberg's presence at the protest site, which supports the claim of her involvement.
However, details about the extent of her participation in the protests remain unspecified. It is unclear whether her visit was brief or if she actively participated in the demonstrations.
Verdict: Probable. While her presence at the protest site is confirmed, the nature of her involvement in the student protests at Paul Eluard high school remains unclear.
