The Royal Academy of Arts has been accused of displaying anti-Semitic artwork inspired by the war in Gaza for a second time.

Jewish visitors said they had been left upset by two pieces of artwork by Michael Sandle, a Royal Academy member, that were still on display at the Summer Exhibition as of Friday.

One £6,000 piece in the display titled “Terrorist versus smiling mass murderer of innocents”, shows what appears to be a Hamas member standing next to an Israeli air force pilot with a damaged building in the background.

A second work, titled “Apropos terror – a pilot doesn’t hear the screams of the women and children he is massacring with impunity”, is a slightly larger version of the first piece and priced at £25,000.

Caroline Turner, the director of UK Lawyers for Israel (UKLFI), wrote to Natasha Mitchell, the Royal Academy’s interim secretary and chief executive, calling for them to be removed.

Ms Turner wrote: “The titles of both these drawings imply that Israel is purposely slaughtering women and children.”

“This is far from the truth, since the Israeli army does all it can to avoid harming women and children, while targeting Hamas terrorists, who unfortunately use women and children as human shields,” the letter added.
