Foreign Minister Mohammad Javad Zarif was given a hero's welcome by a jubilant crowd as he landed in Tehran Friday after Iran and six world powers reached a framework nuclear deal that could ease crippling sanctions on the Islamic Republic. Residents took to the streets late Thursday, waving flags from cars to celebrate the outline agreement, which sets the stage for work on a final accord over the next three months. "We are very happy, so happy," one local resident said. Following eight days of talks in Lausanne, Switzerland, Iran agreed to curbs on its uranium enrichment program, and it agreed to convert one enrichment plant into a research facility, the State Department said. International inspectors will have regular access to all Iranian nuclear facilities. In exchange, world powers said they would begin to lift punishing economic sanctions on the country once the inspectors have verified that it has made good on the agreement.
