White South African farmer Nigel Ralfe was at his family farm when four men appeared asking to buy milk. When he told them he had none to sell, he was shot at point blank range, and had to watch as his wife, Lynette, was shot dead.

The attack happened three weeks ago, when Nigel Ralfe was in his farm office in KwaZulu-Natal.

The bullet went into his left arm, disabling him, and he was then badly beaten.

When the men demanded money, they made him take them to his house, but as his wife opened the door they shot her with a fatal bullet.

As all of this was happening, Nigel's three small granddaughters entered the room and saw him covered in blood - he had to persuade them to stay calm, go to their bedroom and shut the door.

Thankfully, the nightmare finally ended when the attackers suddenly left, leaving Nigel able to summon help.

The local police are now investigating, and two men have been arrested.

The attack on Nigel Ralfe's farm was one of three similar attacks in just a single weekend in rural South Africa.

Since apartheid was banned in 1994, more than 3000 white farmers have been killed.

And now the issue has been further highlighted by recent tumultuous events.

Last weekend saw the murder of the white supremacist leader Eugene Terreblanche. And last month wide discussion was sparked when the head of the ANC Youth League, Julius Malema, opened a public rally by singing an apartheid era anthem with the words, "kill the boer."
