The Organisation of Islamic Cooperation (OIC) has declared East Jerusalem as the capital of Palestine, rejected the US stance as "dangerous" and called on the international community to follow in its footsteps.
At a summit held in Turkey a week after US President Donald Trump declared Jerusalem as Israel's capital, the group of Muslim leaders on Wednesday called on all countries to "recognise the State of Palestine and East Jerusalem as its occupied capital".
In a statement, the OIC added that the 57-member group remains committed to a "just and comprehensive peace based on the two-state solution".
It also called on the UN to "end the Israeli occupation" of Palestine and declared Trump's administration liable for "all the consequences of not retracting from this illegal decision".
"[We] consider that this dangerous declaration, which aims to change the legal status of the [city], is null and void and lacks any legitimacy," the group said.
Marwan Bishara, Al Jazeera's senior political analyst, said the summit in Istanbul highlighted that Palestinians, Arabs and Muslims continue to be committed to peace.
"Now, Muslim countries in addition to a whole lot of others that arallied with the Palestinian cause will recognise Jerusalem as the capital of Palestine," he said.
"And those Islamic countries are ready to sever relations to punish any one country that follows in the footsteps of the United States in recognising Jerusalem as the capital of Israel."
Situation of instabilitySpeaking earlier on Wednesday, Yousef al-Othaimeen, the OIC's secretary general, rejected the US decision and urged Muslim leaders to work together to present a united response to the move.
"The OIC rejects and condemns the American decision," he said. "This is a violation of international law ... and this is a provocation of the feelings of Muslims within the world.
"It will create a situation of instability in the region and in the world."
Speaking before al-Othaimeen, Palestinian President Mahmoud Abbas said the US had "disqualified" itself from future Israel-Palestine peace talks after proving its "bias in favour of Israel".
Founded in 1969, the OIC bills itself as "the collective voice of the Muslim world".
Trump announced on December 6 that the US formally recognises Jerusalem as the capital of Israel and will begin the process of moving its embassy to the city, breaking with decades of US policy.
The decision violated international law, according to Abbas. "We shall not accept any role for the United States in the peace process, they have proven their full bias in favour of Israel," he said.
"Jerusalem is and always will be the capital of Palestine."
Palestinians envisage East Jerusalem as the capital of a future state. Israel, meanwhile, says Jerusalem, which is under Israeli occupation, cannot be divided.
The comments by Abbas, president of the Palestinian Authority (PA) were seen as his strongest yet on the issue.
Al Jazeera's Hoda Abdel-Hamid, reporting from Ramallah, said Palestinians were "very frustrated" after seeing "many agreements and many condemnations" but "nothing really changing for them on the ground".
"When you ask them who they hold responsible for that, they say certainly the PA, their own leadership," she said, citing Palestinians' disappointment about the disunity among their different political factions.
