The event, organised by Iran's "House of Cartoons", will highlight the crimes committed by the extremist group, Tehran's Press TV reports . "In order to reveal the true nature of IS we decided to hold this contest and have people submit their cartoons or caricatures. IS tries to associate itself with Islam, but its essence has no idea about Islam", Massoud Shoja'ei Tabatabai, the head of House of Cartoons, told the Iranian TV. Some of the cartoons shown by the TV portray Western countries, especially the US, as supporters of the Islamic State, and there are plans to exhibit the best entries in Iraq, Syria and Lebanon.
