Iranian President Ebrahim Raisi will travel to Saudi Arabia on Sunday, the Etemadonline news website has reported.

According to Reuters, it will be the first visit by an Iranian head of state since Tehran and Riyadh ended years of hostility under a China-brokered deal in March.

“President Raisi will attend the Organisation of Islamic Cooperation’ (OIC) summit in Riyadh, where the issue of Palestine will be discussed,” the Iranian website reported.

Regional rivals Tehran and Riyadh agreed to resume ties in March under a deal negotiated by China after seven years of hostility, which had threatened stability and security in the Gulf and helped fuel conflicts in the Middle East from Yemen to Syria.
