Protests are taking place in cities around the world in response to the detention of 30 Greenpeace activists in Russia, including two from New Zealand.
Greenpeace is calling for a day of "global solidarity" for the activists, who were charged with piracy after a protest at a Russian oil platform in the Arctic.
Starting with about 100 demonstrators outside the Russian embassy in Wellington on Saturday, the protests are being staged around the world.
The entire crew of the ship Arctic Sunrise ,was arrested on 18 September after two activists tried to board the Russian state-controlled oil platform in the Pechora Sea.
The crew including New Zealanders David Haussmann and Jonathan Beauchamp have all been charged and are being held in the port of Murmansk, in northwest Russia, facing prison terms of up to 15 years.
Six of the arrested crew are from the UK, and others charged are from countries including Argentina, Australia, Canada, France, Zealand, Russia, and the US.
In London, actor Jude Law and musician Damon Albarn have joined hundreds demonstratingoutside Russia's embassy.
Protesters stood behind banners declaring, "Free the Climate Defenders", "Journalist and Not Pirate", and "Free The Arctic 30".
Other Greenpeace protests took place in Madrid, Brussels, Moscow, Mexico City, Sao Paulo and Istanbul.
Australia raises concerns
Australian Foreign Minister Julie Bishop has officially registered concerns with the Russian government over the treatment of an Australian Greenpeace protestor.
Ms Bishop had talks on Saturday on the sidelines of the APEC meeting in Bali with Russia's deputy foreign minister Igor Morgulov.
She says foreign affairs officials will hold further talks in Russia this week on the case of Australian Colin Russell.
Ms Bishop says the view of Russian authorities that the protest was a breach of their law will have to be challenged.
