Turkish President Recep Tayyip Erdogan convened in Istanbul an emergency summit of the world's main pan-Islamic body, the Organisation of Islamic Cooperation (OIC), seeking a coordinated response to the recognition by US President Donald Trump of Jerusalem as Israel's capital.
With the Islamic world itself mired in division, the summit fell well short of agreeing any concrete sanctions against Israel or the United States.
But their final statement declared "East Jerusalem as the capital of the State of Palestine" and invited "all countries to recognise the State of Palestine and East Jerusalem as its occupied capital."
They declared Trump's decision "null and void legally" and "a deliberate undermining of all peace efforts" that would give impetus to "extremism and terrorism."
Jerusalem's status is perhaps the most sensitive issue in the Israeli-Palestinian conflict.
Israel sees the entire city as its undivided capital, while the Palestinians want the eastern sector, which the international community regards as annexed by Israel as the capital of their future state.
Erdogan -- who regards himself a champion of the Palestinian cause -- denounced Israel as a state defined by "occupation" and "terror", in a new diatribe against the Israeli leadership.
"With this decision, Israel was rewarded for all the terrorist activities it has carried out. It is Trump who bestowed this award even," said Erdogan, who holds the rotating chairmanship of the OIC.
He said all countries who "value international law and fairness" should recognise occupied Jerusalem as the capital of Palestine," saying Islamic countries would "never give up" on this demand.
'No More Role For US'
Using unusually strong language, Abbas warned that there could be "no peace or stability" in the Middle East until Jerusalem is recognised as the capital of a Palestinian state.
Moreover, he said that with Trump's move the United States had withdrawn itself from a traditional role as the mediator in the search for Mideast peace.
"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.
The final statement from the OIC echoed this sentiment, saying Trump's move was "an announcement of the US administration's withdrawal from its role as sponsor of peace" in the Middle East.
But bridging the gaps in a Muslim political community that includes arch rivals Sunni Saudi Arabia and Shiite Iran was always a tall order, let alone announcing any concrete measures agreed between the 57 OIC member states.
Several key players, like Egypt, Saudi Arabia and the United Arab Emirates, were unlikely to want to risk their key relationship with Washington for the sake of an anti-Washington OIC statement.
Iranian President Hassan Rouhani, Jordanian King Abdullah II and Lebanese President Michel Aoun were among the heads of state present, as well as the emirs of Qatar and Kuwait and presidents of Afghanistan and Indonesia.
The level of Saudi representation -- critical if the final statement is to carry long-term credibility -- was only at the level of a senior foreign ministry official.
"Some countries in our region are in cooperation with the United States and the Zionist regime and determining the fate of Palestine," seethed Rouhani, whose country does not recognise Israel and has dire relations with Saudi Arabia.
But as the summit was being held, Saudi King Salman in Riyadh echoed the calls over Jerusalem, saying it was the "right" of the Palestinians to establish "their independent state with East Jerusalem as its capital".
Sudanese President Omar al-Bashir, who is wanted by the International Criminal Court for genocide and war crimes, was also in attendance and warmly greeted by Erdogan.
A surprise guest was Venezuela's leftist President Nicolas Maduro whose country has no significant Muslim population but is a bitter critic of US policy.
Trump's announcement last week prompted an outpouring of anger in the Muslim and Arab world, where tens of thousands of people took to the streets to denounce the Jewish state and show solidarity with the Palestinians.
The decision sparked protests in Palestinian territories, with four Palestinians killed so far in clashes or Israeli air strikes in response to rocket fire from Gaza and hundreds wounded.
