Kerry Headed Home Without Reaching Nuke Deal

(Vienna) -- Secretary of State John Kerry is heading back to Washington without nailing down a deal on Iran's nuclear program.
He was taking part in talks among six world powers in an effort to determine how far Iran can take its nuclear program. Kerry met privately with Iran's foreign minster several times during his trip to Vienna and says, while there has been progress, significant hurdles remain. The U.S. has set a July 20th deadline to strike a deal, but could extend that time frame if talks gain momentum.
