The summit will focus on Palestinian-Israeli conflicts, the Syrian crisis especially after an alleged chemical attack and the US-led airstrikes, Yemen's civil war, as well as fighting against terrorism, Xinhua news agency reported.
UN Secretary General Antonio Guterres, AL Secretary General Ahmed Aboul-Gheit and Chairman of the African Union Commission Moussa Faki and High Representative of the European Union for Foreign Affairs and Security Policy Federica Mogherini are also participating in the one-day summit.
"The Palestinian case is our priority and will remain so until all the Palestinians gain their rights," he said, stressing that East Jerusalem is the capital of Palestine.
The king also denounced Iran's interference in other states' internal affairs by committing "terror acts", calling for the unity of the Arab world against it.
He believed there has been a huge setback in the process of solving the Palestinian-Israeli conflict after US President Donald Trump's announcement.
On December 6, 2017, Trump announced his official recognition of Jerusalem as Israel's capital and instructed the relocation of the US Embassy from Tel Aviv to the disputed holy city, which promptly triggered fury and condemnation throughout the Arab world.
The situation has become even worse since the beginning of the six-week "Great March of Return" rally by Palestinians on March 30, where 32 Palestinians have been killed and more than 3,000 injured in clashes with Israeli soldiers in the Gaza border areas.
"So it is important to support Palestinians and (Palestinian President) Abbas," Aboul-Gheit said.
