VIENNA (Reuters) -- A U.S.-Iranian deal taking shape to revive Iran's 2015 nuclear agreement with world powers lays out phases of mutual steps to bring both sides back into full compliance, and the first does not include waivers on oil sanctions, diplomats say.
Envoys from Iran, Russia, China, Britain, France, Germany, the European Union and the United States are still negotiating details of the draft accord amid Western warnings that time is running out before the original deal becomes obsolete. Delegates say much of the text is settled but some thorny issues remain.
