Across the globe, millions of people, mostly students and children, have taken part in demonstrations calling for more urgent action from their governments to tackle climate change.
The protests, inspired by Swedish teenage activist Greta Thunberg, started in the Pacific islands and then continued across Australia, Japan, Southeast Asia before moving on to Europe, Africa, the Middle East and the Americas – 139 nations in all.
Young people stayed away from school while employees did not go into work during the day of mass protests.
