Iran, US, Europe start implementing nuclear deal

TEHRAN, Iran (AP) — Iran unplugged banks of centrifuges involved in its most sensitive uranium enrichment work on Monday, prompting the United States and European Union to partially lift economic sanctions as a landmark deal aimed at easing concerns over Iran’s nuclear program went into effect.

The mutual actions — curbing atomic work in exchange for some sanctions relief — start a six-month clock for Tehran and the world powers to negotiate a final accord that the Obama administration and its European allies say will be intended to ensure Iran cannot build a nuclear weapon.
