Greenpeace climbers abseiled from the roof of Naples’ San Paolo stadium during half-time in the home team’s game against Arsenal, unfurling a vertical banner right above the VIP stand reading “Giustizia per Cristian” (Justice for Cristian). Cristian is one of the 'Arctic 30' currently detained in Russia following a peaceful protest against Gapzrom's Arctic oil drilling plans last September. Gazprom, Russian oil giant and one of the sponsors of the event, is racing to become the world’s first oil company to commercially exploit oil reserves in the ice-covered waters of the Arctic. Greenpeace is campaigning for a ban on offshore drilling in the Arctic, and for the uninhabited area around the North Pole to be declared a global sanctuary.
