> But despite the tough talk, countries such as Egypt and Saudi Arabia only sent ministers, and the old Sunnis Shia tension hangs over the conference.
Wednesday's summit was hosted by the Turkish president, who's called the Arab response to the move so far, weak. I'm Reuters correspondent Emily Wither, at the Islamic Summit, where more than 50 Muslim leaders are holding discussions. Turkey has seen some of the largest street protests since the US announcement.
And the country's President, Tayyip Erdogan, has been one of Trump's harshest critics. He says this gathering marks a turning point. For the masses out on the streets here, and elsewhere around the world, they'll likely be disappointed if this summit doesn't produce a plan of what to do next.
Israel captured Arab East Jerusalem in 1967 and later annexed it. An action not recognized internationally. Turkey is urging Muslim nations to pressure the world to recognize East Jerusalem as the capital of the Palestinian State. Erdogan telling leaders, Trump's decision was a reward for Israeli actions, including occupations, settlement construction, and land seizure.
The Summit is issuing a strong rejection of the US decision but little else on how to move peace talks forward.
