Saudi Arabia has summoned Sweden’s ambassador to denounce the Quran-burning incident outside a Stockholm mosque that sparked a diplomatic backlash across the Muslim world, state media reported early Monday.

The kingdom — home to the holiest sites in Islam, in Makkah and Madina— had already condemned Wednesday’s incident in which an Iraqi citizen living in Sweden, Salwan Momika, 37, stomped on the Muslim holy book and set several pages alight.

The foreign ministry summoned the ambassador on Sunday to urge Sweden “to stop all actions that directly contradict international efforts seeking to spread the values of tolerance, moderation and rejection of extremism, and undermine the necessary mutual respect for relations between peoples and states”, the official Saudi Press Agency reported.

Momika’s Quran burning coincided with the start of the Eid ul Adha holiday and the end of the annual Hajj pilgrimage in Saudi Arabia, triggering widespread anger.

Countries including Iraq, Kuwait, the United Arab Emirates and Morocco have also summoned Swedish ambassadors in protest.

Iran said on Sunday it was holding off on sending its new ambassador to Sweden because of the incident.

At an extraordinary meeting on Sunday at its Jeddah headquarters, the Saudi-based Organisation of Islamic Cooperation called for collective measures to avoid future Koran burnings.

Swedish police had granted Momika a permit in line with free speech protections, but authorities later said they had opened an investigation over “agitation against an ethnic group”, noting that Momika had burnt pages from the Islamic holy book very close to the mosque.

Sweden’s government condemned Momika’s actions on Sunday, calling them “Islamophobic”.
