Climate activist Greta Thunberg appeared at London's Westminster Magistrates Court on Wednesday, November 15, charged with a public order offence over an environmental protest in central London last month.

The 20-year-old was detained by police on October 17 after she and dozens of demonstrators locked arms to obstruct the entrances to a hotel where an oil and gas conference was taking place.
