Hunger strike for fibre

Oklahoma City bombing conspirator Terry Nichols says he's going on a hunger strike because he claims prison officials don't provide him a fibre-rich diet.

Nichols is serving life for conspiracy and involuntary manslaughter in the 1995 federal building bombing that killed 168 people.

Timothy McVeigh was convicted of murder and executed.

Nichols said in a handwritten note filed in Denver federal court yesterday that he began his strike on Monday because his body is being "defiled" by the food he gets at the federal Supermax prison in Colorado.

Nichols is representing himself in a pending lawsuit about his diet.

He says the lack of whole grains and fresh food in his diet harms his health and violates his religious beliefs, causing him to "sin against God".
