Who are Extinction Rebellion?
The group was launched last year and since then its members have forced bridges and roads to close, and even poured buckets of fake blood outside Downing Street.
The group has three demands: for the government to “tell the truth about climate change”, reduce carbon emissions to zero by 2025, and create a citizens’ assembly to oversee progress.
As part of Extinction Rebellion’s protests the group has been trying to get arrested as much as possible because they think it will help with their demands. Some people say, however, that the group causes unnecessary disruption and wastes police time when forces are already overstretched.
