A 91-year-old Ukrainian man has been sentenced to five years in prison for his part in the killing of 28,060 Jews at a Nazi extermination camp in 1943.

John Demjanjuk was convicted of being an accessory to mass murder for his actions as a guard at the Sobibór concentration camp in occupied Poland, where he herded Jews to their death in the camp's gas chambers.

Demjanjuk sat in a wheelchair before the judges as they announced their verdict, but showed no reaction.
