Alexei Navalny, the leader of the Russian opposition who is currently in jail, comes out with some darkly funny words.

Alexei Navalny, the leader of Russia's opposition, made a sarcastic statement on Tuesday about being sent to a prison colony in the Arctic called the "Polar Wolf." This was his first public showing since people stopped talking to him three weeks ago.

Navalny is President Vladimir Putin's most well-known and persistent internal enemy. He is currently serving a 19-year sentence for extremism. He was in jail in Vladimir,

which is in central Russia and about 230 kilometers (140 miles) east of Moscow. But on December 6, his friends said he couldn't be found.

Monday, they said that they had found him in the Yamalo-Nenets region, which is about 1,900 kilometers (1,200 miles) northeast of Moscow and is known for having very bad conditions in its jail colony.

In a tweet, Navalny said, "I am your new Santa Claus." He was talking about his location above the Arctic Circle in the jail in the town of Kharp.

The area is known for having long, harsh winters. About 100 kilometers (60 miles) away is Vorkuta, whose coal mines were some of the worst jail camps in the Soviet Gulag.

Although Navalny is known for making very funny comments, he said he was in a good mood after being moved to the new prison.

However, he said the northern winter darkness is discouraging: "I don't say 'Ho-ho-ho,' but I do say 'Oh-oh-oh,' when I look out of the window and see night, then evening, and then night again."
