Muslim leaders have held an emergency summit in Istanbul to try and forge a united stance against US President, Donald Trump's recognition of Jerusalem as the capital of Israel.
Turkey's President Erdogan called on world powers to recognise Jerusalem as the capital of Palestine and said the United States should reverse its decision.
"As Islamic countries, we will never give up on our demand of a sovereign and independent Palestine with Jerusalem as it’s capital."
Palestinian President Mahmoud Abbas called it a crime which showed that Washington should no longer play a role in Middle East peace talks.
King Abdullah of Jordan, which signed a peace treaty with Israel more than 20 years ago, said he rejected any attempt to change the status quo of Jerusalem.
"My dear friends, Jerusalem is most holy in Islam. It is in the hearts of all Muslims, as it is in the hearts of all Christians. Our right - Muslims and Christians - to Jerusalem is eternal."
Dozens of protesters gathered near the venue hosting the 57-member Organisation of Islamic Cooperation (OIC) to denounce Trump's decision to recognise Jerusalem as Israel's capital.
The protesters, who responded to a call by the Turkish NGO Humanitarian Relief Foundation, or IHH, chanted anti-US slogans and wore masks with the Al-Aqsa Mosque.
