Anders Behring Breivik Retuers

Norwegian mass murderer Anders Behring Breivik has apparently taken a page from the book of Palestinian Arab terrorists, threatening to go on a hunger strike if his conditions in jail aren't improved.

Breivik said he's been held in isolation since September 2 and only allowed out of his cell for one hour a day, according to local media reports cited by BBC.

Breivik was sentenced to 21 years in jail back in 2012 for murdering 77 people, mostly youths, by planting a bomb outside Oslo's main government building and later opening fire on a leftist youth camp on the island of Utoya. He conducted the attacks in July of 2011.

The mass murderer is suffering from poor prison conditions leading him to threaten the hunger strike, according to a letter he released to Norwegian and Swedish media.

In the letter, he said that if his conditions did not improve he would hunger strike until he died.

A major complaint of his is that his solitary confinement has made it impossible for him to continue studying in a political science course at the University of Oslo.

He enrolled as a full student of the university from jail back in July, after applying back in 2013 in a request that caused uproar.

"Studying and corresponding is not humanly possible under such circumstances, and this applies to anyone who is isolated under such conditions," wrote Breivik in his letter threatening the hunger strike.
