Two elderly Holocaust survivors have been savagely beaten in a sickening robbery and anti-Semitic attack in the Netherlands.

Dutch police have launched an investigation after two armed men claiming to be police officers forced their way into the Amsterdam home of Shmuel Blog, 87 and his wife Diana, 86.

The criminals called the elderly couple 'dirty Jews' and demanded they hand over valuables before the savage attack, which left Mr Blog blind and confined to a wheelchair for life after breaking his thigh. Mrs Blog is also expected to spend the rest of her life in a chair suffering from 'extreme pains'.

The Blogs told Dutch police officers that two men dressed entirely in black knocked on their front door and identified themselves as police officers on August 4, according to the Times of Israel.

When Mr Blog answered the door the pair burst in, pointing their guns and hitting and kicking the elderly couple as they demanded jewelry and other valuables.

Severely injured, the elderly couple were then tied up and stripped of the rings and other jewelry they were wearing.

'They called us "dirty Jews" and said: "You don't need your jewelry anymore. You've been wearing it for too long. Now it's all ours",' Mrs Blog told Ynet.

'They wanted to chop off my finger because the rings didn't come off fast enough,' she added.

Since the brutal attack last month, Mr and Mrs Blog - who have been married for 56 years - have been forced to live in an Amsterdam rehabilitation centre.

Police have issued an appeal for information and the couple's son put up €10,000 reward, but so far nobody has been arrested. The reward money has grown by several thousand pounds over the past few days as outraged members of the public react to Dutch media coverage of the attack.

Both Blogs are Holocaust survivors, with Mrs Blog still carrying the scars she got being attacked by guard dogs as a young woman at Auschwitz concentration camp.

In a statement, the Dutch Embassy in Israel told Ynet, 'This is a shocking incident, a brutal robbery that extremely affected the victims.'

'In general, it's important to emphasize that everyone should feel safe in the Netherlands. We will not tolerate any incident of discrimination and anti-Semitism,' they added.
