Global Climate Strike: Millions protest around the world
Millions of people - overwhelmingly children and teenagers – have taken to the streets around the globe, calling on their governments to take serious action to tackle climate change.
The climate strike rallies have been led by schoolchildren and was sparked by campaigner Greta Thunberg - the Swedish teenager who inspired a global climate movement with her solitary protests last year.
Protesters across continents waved placards and chanted slogans in what could be the biggest ever demonstration over global warming caused by humans. Gabriel Gatehouse reports.
