Iran, world powers agree 'historic' framework nuclear deal

Iran and world powers agreed April 2 on the framework of a potentially historic deal aimed at curbing Tehran?s nuclear drive after marathon talks in Switzerland.
 
It marks a major breakthrough in a 12-year standoff between Iran and the West, which has long feared Tehran wants to build a nuclear bomb.
 
US President Barack Obama welcomed the "historic understanding" with Iran but cautioned more work needed to be done.
 
"If Iran cheats, the world will know it," he said in a televised address from the White House.
 
After eight days of talks that sometimes went through the night, Iran agreed to curtail its nuclear programme in return for the lifting of punishing sanctions, said EU foreign policy chief Federica Mogherini.
 
The main outlines agreed at the negotiations in the Swiss city of Lausanne now have to be finalised in a highly complex agreement by June 30.
 
US Secretary of State John Kerry hailed a "big day", saying on Twitter that the global powers and Iran "now have parameters to resolve major issues on nuclear program. Back to work soon on a final deal".
 
Iranian President Hassan Rouhani said the drafting of a full agreement would begin immediately with the aim of completing it by the June 30 deadline.
 
 Iranian media said the deal will include Iran slashing by two-thirds, to 6,000 from 19,000, the number of centrifuges, which can make fuel for nuclear power but also the core of a nuclear bomb.
 
Mogherini said the United States and the EU will lift all nuclear-related sanctions on Iran once the UN atomic agency has verified that Tehran has stuck to the ground-breaking deal.
