The secretary of Iran's international cartoon contest on the Holocaust said the event is not meant to deny the killing of millions of Jews by Nazi Germany during World War II.
"We do not want to deny or prove anything," Massud Shojai Tabatabai said on May 14.
He spoke at the launch of the contest in Tehran where some 150 works from 50 countries, including France, Turkey, and Yemen, are on display.
The works mainly criticize what they consider the use of the Holocaust by Israel to distract from the Palestine issue.
Former Iranian hard-line President Mahmud Ahmadinejad had repeatedly questioned the killing of 6 million Jews across Europe during World War II.
But his successor, President Hassan Rohani, has distanced himself from those comments.
Cartoonists from around the world are competing in the contest which is organized by nongovernmental bodies with strong support from Iran's hard-liners.
Prizes range from $5,000 to $12,000 for the top three entries.
