A boat rowed by Greenpeace activists sailed along the Moscow River on Nov 6, with the objective to draw people's awareness about 30 Greenpeace activists - the Arctic 30 - who were imprisoned in Russia. The boat had a flag which says "Free the Arctic 30!"

The "Arctic 30" were crew of the Arctic Sunrise who were arrested on Sept 19, 2013. These crew protested against a Russian-owned offshore oil rig Gazprom. The group resisted the oil rigging from the Arctic because of oil spills risk.

On Nov 6, The International Tribunal for the Law of the Sea began its trial to the 30 Arctic Sunrise crews. However, Russia had failed to attend the trial and was the very first country to have done so.

Among this 30 crew members locked up in prison in Russia (and now denied trial by Russia), was Alex Harris, a 27-year-old resident of Sydney.

In a letter obtained by the Sydney Morning Herald, Ms Harris penned her loneliness as she suffered a "prison coma" inside Russian prison. She wrote that on being alone in the cell, she would tap on the wall to communicate with fellow prisoner Camila Speziale.

In a letter addressed to the other Australian Greenpeace colleagues, Ms Harris describe that being inside the cell for six weeks, she was "losing track of time".

''The days are blending into one. The 25th day is just as tortuous as the first... when I am feeling low I dance; I also tap on the wall of my cell, Camila taps back and I'm reminded that I am not alone.''

Although allowed to walk outside for brief period of time each day, Ms Harris wrote that the northern winter made the situation all the more depressing.

''... when I go outside my toes go numb ... the falling snow flakes on my face awaken me from my prison coma... steel bars digging into my back, facing the same four green walls'' is the hardest part of the day, Ms Harris said in the letter.

The Greenpeace Australia accused Canberra of not doing its best in order to release the Arctic 30 while British Prime Minister David Cameron had already phoned Russian leader Vladimir Putin on Tuesday to discuss the situation of the Arctic 30. German leader Angela Merkel had also raised her concerns to Mr Putin. The French Government had also done its part of reaching out to Russia's Prime Minister.

According to Foreign Affairs Minister Julie Bishop said that she had called the attention of Russian Foreign Ministry and was "currently managing more than 1300 active consular cases around the world."

Meanwhile, the Dutch government representative Liesbeth Lijnzaad alleged that with Russia's neglect to attend trial on Nov 6, the country had violated the human rights of the Arctic 30 and that these crew members were being detained without grounds.

Russia on the other hand claimed that the Arctic 30 posed security threat and hence charged them with hooliganism. When convicted of Hooliganism, the Arctic 30 will serve seven years in jail.
