The climate activist Greta Thunberg mocked world leaders, accusing them of saying nothing more than "blah, blah, blah" when it came to their commitments to tackle the climate crisis.

Speaking at the Youth4Climate summit in Milan, Italy, on Tuesday, Thunberg said: "Build back better. Blah, blah, blah. Green economy. Blah blah blah. Net zero by 2050. Blah, blah, blah."
