One day after the caricature sparked outrage among Jewish groups for its depiction of a bloodthirsty Prime Minister Benjamin Netanyahu building a wall with the blood and bodies of Palestinians, leading Israelis joined the chorus of condemnation.

"The newspaper should apologize for this. We're not going to let this stand as it is," Israeli Ambassador to London Daniel Taub told The Times of Israel in a telephone interview. "We genuinely think that a red line has been crossed and the obligation on the newspaper is to correct that."

Taub added that he was going to meet with the newspaper's editor "at the earliest opportunity, perhaps already today," to express the government's concern about a cartoon that draws "on classical anti-Semitic themes."

In a meeting Monday with Prime Minister Benjamin Netanyahu, Tony Blair, the representative of the Middle East quartet who's also a former British premier, deplored the caricature, noting the timing of its publication on International Holocaust Remembrance Day, according to a press release from the Prime Minister's Office.
