Swedish climate activist Greta Thunberg received Amnesty's "Ambassadors of Conscience Award" in Washington DC on Monday and said 'no-one is too small to make a difference'.

The 16-year-old, who is taking a year out of high school, received a standing ovation as she addressed students at The George Washington University  where the ceremony was held.

"The politics required to take on this crisis simply doesn't exist today," she said.

Thunberg, and her "Friday's For Future" youth movement, join the likes of Nelson Mandela and Malala Yousafzai in receiving Amnesty International's highest award, which celebrates individuals and groups who have furthered the cause of human rights by acting on their conscience, confronting injustice.
