Thunberg joins hundreds at climate strike in Stockholm

STORY: Demonstrators walked with banners and signs while chanting slogans in a march through central Stockholm.

Thunberg said the theme of the demonstration organized by Fridays for Future was "climate justice now," the same demand she said they had been repeating for the last five years.

"It's nothing new, it's the same thing as scientists and the most affected people have been warning us about for many decades now and we are just repeating that message once again," Thunberg said.
