Israeli officials have now announced that Amir will be allowed to join a normal prison community, on the basis that the reasons for keeping him separate are no longer valid.
Amir will not move to an open prison ward. Instead, he will be held in a cell with two to four fellow inmates, and will have two hours every day to meet with other inmates in the prison yard.
It will also mean he is now able to watch television and use a telephone more often.
Many believe that, had Rabin not been murdered, peace would have been acheived in the region. The decision to release Amir from confinement is likely to be controversial among Israelis.
Amir has never expressed any remorse for his actions.
