A Man harassed by anti-war mail after his son was killed in Afghanistan says immigrants who can't adapt to Australian life and values should live elsewhere.
Private Gregory Michael Sher, 30, was killed in a rocket attack in Oruzgan Province, in southern Afghanistan, in January.
He was the eighth Australian Defence Force soldier to be killed in Afghanistan since 2002, but the first to die as a result of indirect fire.
Mr Sher's father Felix received a phone call and letters, allegedly from self-styled Muslim cleric Sheikh Haron, just before his son's funeral.
"I feel bad that you have lost your son but I don't feel bad that a murderer of innocent civilians has lost his life," a line in one of the letters reportedly said.
