Police are investigating reports that a group of Jewish school children heading home on a bus were victims of a vicious anti-Semitic attack by a group of teenagers in Sydney.

The children, aged between five and 12, were distraught after the men boarded the bus headed to Bondi Junction on Wednesday afternoon and begun screaming anti-Semitic abuse, a mother of three of them says.

Jacqui Blackburn has told The Daily Telegraph her three terrified daughters called her saying: “Please help us mummy, there’s eight drunk men that have just been let onto our school bus.

“They’re screaming, `heil Hitler, kill the Jews … we’re going to cut your throats’ … then the phone cut off.”

Jewish people have a right to live without fear or favour. Less is completely unacceptable http://t.co/t3C8nccvdx pic.twitter.com/RtaytiJdEY

NSW Communities Minister Victor Dominello says he is deeply disturbed by the reports.

“Public abuse and intimidation on the grounds of race or religion is deplorable,” he said.

“The people of NSW will never excuse it and those who are alleged to have subjected school children as young as five to this anti-Semitic attack should face the full force of the law.”

“(The Sydney attack) is sickening,” Vic Alhadeff, the president of the NSW Jewish Board of Deputies told AAP.

“Any racist incident is unacceptable in our society.

“It is particularly sickening when those being targeted are young children.

“There is no place for racism of any form in our society.

“What we saw (on Wednesday) afternoon was taking it to a new low.

Police have appealed for public assistance to find the teenagers, who are described as being aged between 15 and 17.
