US, Other Nations Close To Iran Nuke Deal

According to senior Obama administration official

(CNN) -- The United States and other countries are "getting close" to an interim deal with Iran that would prevent its nuclear program "from advancing, and roll it back" in key areas, a senior administration official said Friday.

Such a deal would "extend the breakout time" that Iran would need to achieve a nuclear weapon and "shorten the time to notice if they tried," the official told reporters.
