Greta Thunberg: 'Leaders failed us on climate change'

"You have stolen my dreams and my childhood with your empty words," she told a UN climate summit in New York.

About 60 world leaders are taking part in the one-day meeting organised by UN Secretary General António Guterres.

He earlier said countries could only speak at the summit if they came with action plans to cut carbon emissions.

US President Donald Trump, a climate change sceptic, had not been expected at the meeting - but he was briefly spotted in the audience.
