Yair Netanyahu, the Israeli prime minister’s son, is under fire for posting an anti-Semitic caricature aimed at his father's critics on social media.

Mr Netanyahu, 26, shared a meme on Facebook captioned "the food chain," which featured a photo of Jewish billionaire George Soros dangling the world in front of a reptilian creature, who in turn dangles an alchemy symbol in front of the pejorative “happy merchant” image.

The other figures in the chain are former Prime Minister Ehud Barak, who has led weekly protests calling on Benjamin Netanyahu to step down over growing corruption allegations.
