London wakes up to another day of climate rebellion
Camps have been set up in the heart of the capital with activists engaging in activities including group reading, playing music and dancing throughout the day.
London police have made nearly 500 arrests as climate-change protesters, labelled "uncooperative crusties" by Prime Minister Boris Johnson, continue the two weeks of announced protests to push for more to be done to protect the environment.
The Extinction Rebellion group has been taking action in several countries including Britain, Germany, Austria, Australia, France and New Zealand as it lobbies politicians to go further in cutting carbon emissions.
The protests are the latest stage in a global campaign for tougher and swifter steps against climate change coordinated by the group, which rose to prominence in April when it snarled traffic in central London for 11 days.
