Hundreds of protesters sign a petition in support of the Arctic 30 and added their painted hand print onto a banner, as a symbol of solidarity for the detainees.

As the Arctic 30 face their 30th day of imprisonment by Russian authorities, nearly 10,000 people are taking to the streets at 85 events in 36 cities to call for their immediate release.

A Russian court has charged the Arctic 30 (twenty-eight Greenpeace International activists, as well as a freelance videographer and photographer), with piracy, punishable for up to 15 years in prison.
