Greenpeace has dismissed Russian claims of finding narcotics and equipment with a possible military use on board their detained ship.
The Russians say they plan to press new charges against the 30 people currently being held accused of piracy after mounting a protest against a Russian owned Arctic oil platform.
On their website the environmentalist group denounced the finds saying the legally stored morphine was for medical use and the equipment was sonar.
Meanwhile in Paris, Greenpeace supporters demonstrated outside the headquarters of Gazprom which owns the oil platform.
They demanded the release of the activists who have been held in Murmansk since September 18 following their protest against Arctic oil drilling.
