For the sake of peace in Middle East, the world must recognise East Jerusalem as the "capital of Palestine", urged Turkish President Recep Tayyip Erdogan on Wednesday.
Palestinian leader Mahmoud Abbas also warned there could be no peace in the Middle East until such a move was made.
Erdogan opened in Istanbul an emergency summit of the world's main pan-Islamic body the Organisation of Islamic Cooperation (OIC), seeking to marshal Muslim leaders towards a coordinated response to the US recognition of Jerusalem as Israel's capital.
Erdogan -- who regards himself a champion of the Palestinian cause -- described Israel as a state defined by "occupation" and "terror".
"With this decision, Israel was rewarded for all the terrorist activities it has carried out. It is Trump who bestowed this award even," he said.
Erdogan added: "I am inviting the countries who value international law and fairness to recognise occupied Jerusalem as the capital of Palestine," saying Islamic countries would "never give up" on this demand.
Meanwhile, Abbas said that United States is no longer the mediator in the peace process between Israel and the Palestinians.
He slammed the recognition by Trump of Jerusalem as the capital of Israel as a "gift" to the "Zionist movement" as if he "were giving away an American city," adding that Washington no longer had any role to play in the Middle East peace process.
"We do not accept any role of the United States in the political process from now on. Because it is completely biased towards Israel," he said.
