A homeless Dubliner who stabbed a 23-year-old to death has today been jailed for nine years.

A homeless man from Dublin who fatally stabbed a 23-year-old who called him a "junkie" and a "scumbag" has said that seeing the dead man's family in court has been sobering.

A murder trial jury has been told that the main issue of the case is whether a 34-year-old Dublin man acted in self-defence when he stabbed a 23-year-old to death last year.
