United Nations General Assembly will hold a rare emergency special session tomorrow at the request of Arab and Muslim countries on US President Donald Trump's decision to recognize Jerusalem as Israel's capital. <br/><br/>Palestinian UN envoy Riyad Mansour said the 193-member Assembly will vote on a draft resolution calling for Mr Trump's declaration to be withdrawn, which was vetoed by the United States in the 15-member Security Council on Monday.<br/><br/>The remaining 14 Security Council members voted in favour of the Egyptian-drafted resolution, which did not specifically mention the United States or Trump but which expressed deep regret at recent decisions concerning the status of Jerusalem.<br/><br/>Palestinian envoy said he hopes there will be overwhelming support in the General Assembly for the resolution. Such a vote is non-binding, but carries political weight. US Ambassador Nikki Haley, in a note on Twitter, warned the United States would remember those who voted for the resolution criticizing the US decision.<br/><br/>Under a 1950 resolution, an emergency special session can be called for the General Assembly to consider a matter with a view to making appropriate recommendations to members for collective measures, if the Security Council fails to act.
