Protests have been taking place in cities around the world, including London, in response to the detention of 30 Greenpeace activists in Russia.
The organisation called for a day of "global solidarity" for the activists, who were charged after a protest at a Russian oil platform in the Arctic.
The entire crew of 30 on board the Arctic Sunrise, from which the protest was launched, have been charged with piracy. Six of the crew are from the UK.
