Pens and pencils were the weapons of choice for artists taking part in an anti-Islamic State cartoon and caricature competition held in Iran.

More than 1,000 images were submitted to Iran’s House of Cartoon competition and 270 were put on display at an exhibition on Sunday.

Artists from more than 40 countries, including the UK and Australia, entered the Daesh (ISIS) International Cartoon and Caricature Contest.

The images, some of them extremely emotive and shocking, have gone on display at cultural centres in Tehran, Iran’s capital.

Graphic artist Massoud Shojaei Tabatabali, head of the House of Cartoon, told Press TV they now have plans to hold the exhibition in other countries like Iraq, Syria and Lebanon.

‘In order to reveal the true nature of ISIL we decided to hold this contest and have people submit their cartoons or caricatures,’ he said.

‘ISIL tries to associate itself with Islam, but in essence has no idea about Islam.’

The contest, launched in February, focuses on the terror group’s horrific crimes, including beheadings, attacks on homosexuals, suicide bombings and the destruction of ancient artefacts.

The artwork will be judged by a team of experts and the winners will be announced on May 31.
