Greenpeace volunteers and supporters protest with a mock prison cell and banners in support of the Arctic 30, Kawah Putih, Bandung, West Java, Indonesia.

At events at 265 cities in 43 countries thousands of people take part in a day of solidarity to mark two months since the Arctic 30 were detained following a peaceful protest against Arctic oil drilling on September 18. A Russian court has charged the Arctic 30 (twenty-eight Greenpeace International activists, as well as a freelance videographer and photographer) with both piracy and hooliganism.
