A Russian court on Thursday jailed a photographer and two Greenpeace activists who were part of the 30-member Greenpeace team protesting near an oil platform in the Arctic last week.

The court on Thursday denied bail and sanctioned a two-month jail term for photographer Denis Sinyakov, Greenpeace spokesman Roman Dolgov and campaigner Paul Ryzincki, pending the investigation. The first two men are Russian, while Ryzincki is Canadian. No charges have been brought against them yet.

The judge has yet to rule in the cases of the other 27 people.

Although Russian President Vladimir Putin said Wednesday the activists aren’t pirates, he defended their detention.
