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 across the world, 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. 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.
