An Israeli cartoonist is responding to Iran's efforts to mock the Holocaust with an unconventional contest of his own: He's asking Jewish artists to draw anti-Semitic cartoons themselves.

Amitai Sandarovich, a cartoonist for the Yediot Ahronot daily, said he came up with the idea for the competition after an Iranian newspaper launched a contest for cartoons about the Holocaust.

"I think that a strong nation needs to know how to laugh at itself, and the Jewish nation has a long history of laughing at itself," Sandarovich said.

The Iranian newspaper said its contest was a response to the publication of caricatures of Islam's Prophet Mohammed in European newspapers. The caricatures have sparked violent protests - sometimes deadly - throughout the Muslim world.

"We have received dozens of messages from Jews all over the world with the message that Jews need to fight fire with humor," Sandarovich said. "We won't burn down embassies or flags or kill or threaten people. We make cartoons that laugh at ourselves."

Sandarovich said he already has received about 100 cartoons. "Some are good and some bad," he said, with most making fun of anti-Jewish caricatures and conspiracy theories commonly found in Arab media.
