Swedish climate campaign star Greta Thunberg was set to meet French President Emmanuel Macron after joining thousands of people at a demonstration in Paris.
The 16-year-old, who has inspired a burgeoning protest movement in Europe and beyond, went to the Elysee with several other youngsters from Belgium, Germany and France.
Thunberg has become a celebrity by skipping lessons every Friday to protest over global warming outside the Swedish parliament.
"When I started the strike I didn’t know what to expect," Thunberg said in Paris. "But it feels incredible and I wish that adults would take more responsibility."
"Kids shouldn’t have to do this," she added.
Thunberg travelled to Paris after a day in Brussels on Thursday, which included another march and a speech in front of EU chief Jean-Claude Juncker.
Euronews journalist Cristina Abellan Matamoros, who was at Friday's march, said: "There's a lot of energy among the youth and older generations.
"The younger generations really want something to be done by politicians and they find it is a crime nothing is being done and want action now."
