Arab and Muslim world leaders to discuss Gaza situation in Saudi Arabia

Leaders from across the Arab and Muslim world - including regional foes Iran and Saudi Arabia - are set to meet in Riyadh on Saturday to discuss the situation in Gaza. 

Late on Friday, the Saudi Foreign Ministry confirmed that the Arab League and the Organisation of Islamic Cooperation summits would be combined.

Riyadh said combining the two summits underscores the importance of reaching a "unified collective position that expresses the common Arab and Islamic will regarding the dangerous and unprecedented developments witnessed in Gaza and the Palestinian territories".

Iranian President Ebrahim Raisi will attend the meeting and make his first trip to Saudi Arabia, ending seven years of severed ties between Riyadh and Tehran. 

It remains unclear what outcome will come from the extraordinary summit, with the Palestinian Islamic Jihad saying they "expect nothing".
