Following the arrest of 21-year-old climate activist Disha Ravi in connection with the dissemination of the Toolkit document, Greta Thunberg on Saturday responded to the arrest and said freedom of speech and the right to peaceful protest are non-negotiable human rights.

"Freedom of speech and the right to peaceful protest and assembly are non-negotiable human rights. These must be a fundamental part of any democracy. #StandWithDishaRavi," Greta Thunberg wrote in a tweet.
