Palestinian President Mahmoud Abbas told Muslim leaders on Wednesday that a US decision to recognize Jerusalem as Israel's capital was a crime which showed that Washington should no longer play a role in Middle East peace talks.
Addressing an emergency meeting of Muslim leaders in Turkey, Abbas said President Donald Trump was giving Jerusalem away as if it were an American city.
"Jerusalem is and always will be the capital of Palestine," he said, adding Trump's decision was "the greatest crime" and a violation of international law.
Wednesday's summit was hosted by Turkish President Tayyip Erdogan who has bitterly criticized the United States, a NATO ally, for its stance on Jerusalem.
Abbas told the leaders in Istanbul that Washington could no longer be an honest broker.
