Islamic leaders united on Wednesday to reject and condemn the U.S. decision to recognize Jerusalem as Israel’s capital. A joint statement was released by the 57-member Organization of Islamic Cooperation, or OIC, after a meeting in Istanbul, Turkey. It said the Muslim leaders rejected and condemned in the strongest terms the U.S. decision, which was announced last week by President Donald Trump. The group’s statement also declared East Jerusalem as the capital of the State of Palestine. It urged all nations to recognize the State of Palestine and East Jerusalem as its occupied capital. Israel captured east Jerusalem in 1967 and has declared all of Jerusalem its capital. But this is not recognized internationally.
