Iran Negotiators Weigh How Long to Stay After Missing Deadline

Iran and world powers weighed how long to extend talks that already have missed their deadline without producing an accord to end the 12-year standoff over the Islamic Republic’s nuclear program.

The negotiations in the Swiss town of Lausanne are still making progress and Secretary of State John Kerry will stay until at least Thursday morning, State Department spokeswoman Marie Harf said Wednesday. His Iranian counterpart Mohammad Javad Zarif called on “all our negotiating partners to seize this opportunity which may not be repeated.”
