'Seize the Moment': Nuke Talks Extended Another Day

Iran and six world powers extended their negotiations on a nuclear deal for yet another day Wednesday, agreeing to resume talks Thursday as Iran called on the global powers to "seize the moment and use this opportunity which may not be repeated." Marie Harf, the State Department's acting spokeswoman, said Secretary of State John Kerry would remain in Lausanne, Switzerland, for at least another day because, as she said, "we continue to make progress but have not reached a political understanding." Top diplomats from Iran and the U.S., Britain, China, France, Germany and Russia have worked well past their midnight Tuesday deadline to agree on a framework for a final accord that would limit Iran's nuclear program, which they hope to sign by the end of June.
