A demonstrator takes part in a silent protest outside the Russian embassy in west London on November 2, 2013, in support of Kieron Bryan, a journalist currently being held in a Russian prison. Kieron Bryan was among 30 environmentalists on board Greenpeace's Arctic Sunrise ship, arrested by Russian forces in a commando-style operation when two activists tried to scale an oil rig on September 18.
