LAUSANNE, Switzerland--Iran and six world powers have agreed on the parameters of a deal meant to block Tehran from developing nuclear weapons in exchange for the lifting of sanctions.
A joint statement read out a news conference in the Swiss city of Lausanne on Thursday said “decisive steps” had been taken in the long-running nuclear negotiations.
The agreement would place strong constraints and controls on Iran’s nuclear program for as many as 25 years, with severe limits for the first decade. The statement said sanctions would be eased after the United Nations nuclear watchdog verifies Iran carried out key commitments.
