1:40 p.m.

The secretary general of the Organization of Islamic Cooperation has called on countries who have not recognized Palestine as a state to do so.

Yousef bin Ahmad Al-Othaimeen told the extraordinary summit of the 57-member states Wednesday that the U.S. decision to recognize Jerusalem as the capital of Israel is "an exceptional challenge" facing Muslim nations. He says the decision will fan violence in the region, giving extremists an excuse to sow chaos.

Turkey is hosting the OIC summit.

Palestinian President Mahmoud Abbas has called on the United Nations to take charge of the Mideast peace process, and revamp it with a new mechanism since Washington is allegedly no longer "fit" for the task.

Abbas spoke at a gathering of Islamic countries hosted by Turkey on Wednesday. The summit is meant to hammer out a united stance in the wake of President Donald Trump’s recognition earlier this month of Jerusalem as Israel’s capital.

Abbas says the Palestinians are committed to a peaceful resolution of the Israeli-Palestinian conflict and will continue to fight violence. But he added that following Trump’s move on Jerusalem, Washington is not accepted as a fair negotiator.

Abbas also said it’s time for countries who accept the two-state solution to recognize Palestine as a state. He urged those who recognize Israel to reconsider, saying the Jewish state has not committed to any international resolution.

He said the U.S. decision on Jerusalem should galvanize Arab, Muslim and Christian support for the city and that it seeks to change the identity of the divided city, which is home to some of the most sacred Muslim sanctuaries.

Palestinian President Mahmoud Abbas says the Palestinians won’t accept any role for the United States in a peace process with Israel "from now on" after the Trump administration’s decision to recognize Jerusalem as the capital of the Jewish state.

Abbas says President Donald Trump’s decision was a "crime" that threatens world peace. He says there will be no peace in the region if the world doesn’t recognize east Jerusalem as the capital of a future Palestinian state.

The Palestinian leader spoke on Wednesday at a summit of Islamic nations hosted by Turkey.

He says the international community has nearly unanimously opposed Trump’s decision, calling it a "provocation" to Muslim and Christian sentiments and saying measures are needed to protect the identity of the divided city.

12:10 p.m.

Turkey’s President Recep Tayyip Erdogan has sharply criticized Israel at the opening of a summit of Islamic nations in Istanbul, calling it a "terror state."

Turkey is hosting the 57-member Organization of Islamic Cooperation on Wednesday in the wake of the U.S. decision to recognize Jerusalem as its capital — a move widely criticized across the world but hailed by Israel. The summit is expected to forge a unified position of Arab and Muslim countries.

Erdogan said in his speech to the gathering that Jerusalem is a "red line" for Muslims who will not accept any aggression on its Islamic sanctuaries. He said East Jerusalem is the capital of a future Palestinian state and called on states that have not recognized a Palestinian state to do so.

Erdogan says the "process to include Palestine in international agreements and institutions should be sped up."

10:20 a.m.

Leaders and top officials of the world’s Islamic nations are coming together in Turkey to try and forge a united stance against President Donald Trump’s recognition of Jerusalem as the capital of Israel.

The summit of the 57-member Organization of Islamic Cooperation is expected to be the strongest unified response yet to Washington’s move by the Muslim world.

Turkey’s foreign minister, Mevlut Cavusoglu, addressed a pre-summit meeting of OIC foreign ministers in Istanbul on Wednesday. He says the U.S. decision aims to "legitimize Israel’s attempt to occupy Jerusalem."

Cavusoglu says the OIC nations "are here to say ‘stop’ to tyranny."

Jerusalem’s status is at the core of the decades-long Israeli-Palestinian conflict and Trump’s Dec. 6 announcement was widely perceived as siding with Israel. It also raised fears of more bloodshed.
