United Nations: The UN Security Council is preparing to ratify the nuclear accord reached between major world powers and Iran by approving a resolution that is expected to be voted on very soon.

A draft of the resolution will be written in Washington on behalf of the P5+1 -- the US, Russia, China, France and Britain, plus Germany and of the European Union, and will be sent to the council "in the coming days," the US ambassador to the United Nations, Samantha Power, said Tuesday.
