Residents of a West Bank Settlement are expected to protest against the arrival of Hagai Amir, the unrepentant brother of the man who killed Israeli Prime Minister Yitzhak Rabin who was released on Friday after serving 16 years and a half in prison.

Amir has never expressed remorse for his complicity in the muder of peace prize hero Rabin, which for many people destroyed an opportunity for peace in the troubled Holy Land. "I am proud of what I did," he said.

His brother Yigal Amir, un ultra-nationalist Jewish extremist, is serving a life sentence for gunning down the prime minister.

Ahead of the release, dozens of activists outside the prison hold sign reading "We won't forgive, we won't forget."

Noa Rothman, Rabin's granddaughter, wrote on Facebook: "Sixteen and a half years have passed and it is painful and insulting as if it was yesterday and I want to scream but what more is left to say?"

Also Dalia Rabin, daughter of the prime minister, spoke out against Amir's release. "My personal feelings are harsh and I have no interest in sharing them," she told Ynet news. "In the case of a prime minister's assassination, it is not the family's place to pass judgement, but the society's.

Members of his family accompanied Amir to the West Bank settlement of Shavei Shomron for the weekend. But residents have been protesting against its arrival.

""Thou shalt not kill," and "Murder - that isn't our way," are some of the signs hanged there.

"This is a completely private visit that people are frowning upon. We can't prevent it, but we're certainly not happy," a Shavei Shomron resident told Haaretz. "That man isn't wanted in the settlement and he would do better to not arrive."

"People like that belong behind bars forever," she said.

Amir was originally condemned to 16 years. The sentence was extended by six months after he was convicted of threatening the life of former Prime Minister Ariel Sharon in 2006. He spent most of his prison years in isolation.

Rabin was assassinated after singing the Oslo accords and a peace treaty with Jordan. Ultra-orthodox Jews accused him of betraying Israel by trading land to the Palestinians for peace.
