Olo Walicki KaszebeII perform at an Arctic 30 solidarity concert organized by Greenpeace Poland in Gdansk, home town of detainee Tomasz Dziemianczuk.

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.
