Obama: Iran nuclear deal limits ability to create nuclear weapons
A historic deal was struck early Sunday between Iran and six world powers over Tehran's nuclear program that slows the country's nuclear development program in exchange for lifting some sanctions while a more formal agreement is worked out. The agreement -- described as an "initial, six-month" deal -- includes "substantial limitations that will help prevent Iran from creating a nuclear weapon," U.S. President Barack Obama said in a nationally televised address. The deal, which capped days of marathon talks, addresses Iran's ability to enrich uranium, what to do about its existing enriched uranium stockpiles, the number and potential of its centrifuges and Tehran's "ability to produce weapons-grade plutonium using the Arak reactor," according to a statement released by the White House. Iran also agreed to provide "increased transparency and intrusive monitoring of its nuclear program," it said.
