MOSCOW, Oct. 9 (Xinhua) -- Moscow has no comments on a letter reportedly sent to President Vladimir Putin by Greenpeace's International Executive Director Kumi Naidoo, which calls for the release of 30 environmentalists, a Kremlin spokesman said Wednesday.
"We can't say anything about that letter's content as we haven't seen it yet," Putin's spokesman Dmitry Peskov told the Interfax news agency, adding that the Kremlin was verifying the existence of the letter.
According to the Greenpeace website, the letter states that "the Arctic is melting before our eyes, and these brave activists stand in defiance of those who wish to exploit this unfolding crisis to drill for more oil."
Greenpeace said the letter was sent via the Russian embassy in the Netherlands.
Over the weekend, Dmitry Borodin, a minister-councilor of the Russian embassy in Netherlands, was held in a police station for allegedly abusing his children and released without charges.
After Putin and the Foreign Ministry strongly protested on Tuesday, the Dutch Foreign Ministry promised to offer its apology if Borodin's diplomatic immunity was violated.
The case comes as the Netherlands and Russia are in a standoff over the seizure of Greenpeace ship Arctic Sunrise that was sailing under the Dutch flag. Some Russian politicians have supposed that Greenpeace and Borodin's cases could be interconnected.
The ship was seized by the Russians in mid-September following the activists' attempt to land on an oil platform in Russia's territorial waters.
On Wednesday, a regional court in the Russian northern Murmansk region remanded more Greenpeace activists in pre-trial detention as their appeal hearing continues through the day.
The court turned down an appeal to release Roman Dolgov, a crew member of the Arctic Sunrise ship. The previous day, the court also refused to release the ship's doctor Ekaterina Zaspa and reporter Denis Sinyakov.
The Murmansk regional court will decide this week over the rest appeals on a district court's ruling to detain until Nov. 24 all 30 members of the Dutch-registered vessel.
