(CNN)Thousands of protesters marched at G7 protests near the French coastal resort of Biarritz to demand action from world leaders.
Protesters descended on the town of Hendaye -- on the French border with Spain -- to protest against economic and climate policies pursued by the world's leading industrial nations, Reuters news agency reported.
Anti-globalization protesters, environmental activists, yellow vest protesters and Basque separatists were among those in attendance, Reuters reported.
G7 summit protest organizers estimate 15,000 people took to the streets, according to a joint statement by umbrella protest organizers Alternatives G7 and G7Ez.
A spokesperson for the Prefecture des Pyrénées Atlantiques, however, told CNN they calculated an estimated 9,000 protesters at the height of the demonstration between the Hendaye and Irun areas.
The leaders of the G7 countries (Canada, France, Germany, Italy, Japan, the United Kingdom and the United States) began three days of talks in Biarritz on Saturday.
