The Saudi secretary-general of the Organisation of Islamic Cooperation (OIC) Iyad Ameen Madani has resigned after his joke addressed to Egyptian President Abdel Fattah al-Sisi caused anger of the authorities of the country, The Daily Mail reported.

The General Secretariat of the Organisation of Islamic Cooperation informed that Iyad Ameen Madani has resigned from his post as Secretary General of the Organisation for health reasons.

 Madani apologized to Egypt, stating that did not want to offend anyone. Meanwhile, Egyptian Ministry of Foreign Affairs declared that it considered the statement serious violation in relation to one of the founders of the organization.

Earlier, OIC Secretary General misspoke, calling the president of Tunisia al-Sisi instead of Essebsi.

“Mr President Beji Caid al-Sisi. Essebsi sorry. This is a big mistake. I'm sure your fridge has more than water, your excellency,” he told the Tunisian leader.

He was referring to widely derided comments made by Mr Sisi earlier last week in which he claimed that his fridge only had water in it for a decade.
