The Arctic 30 have been told they cannot leave Russia and return home for Christmas despite a ruling by an international court ordering their release.
The environmental charity Greenpeace has revealed that Russia investigative committee has written to one of its activists- Anne Mie Jensen from Denmark - indicating that they are not free to leave the country.
A Russian court has begun remand hearings for the Greenpeace activists held on piracy charges today.
The activists crewing The Arctic Sunrise - including 6 Britons - were arrested by the Russian Coastguard on suspicion of piracy during a protest against oil drilling.
The hearing will determine if the activists will remain in custody before a preliminary trial hearing.
