US Secretary of State John Kerry is scheduled to have more nuclear talks with Iranian Foreign Minister Mohammad-Javad Zarif next week, aiming to reach a potential deal by the end of this month.
Kerry's meeting with Zarif, their third in three weeks, is slated for March 15 in the Swiss city of Lausanne, US State Department spokeswoman Jennifer Psaki said on Monday.
She described the upcoming talks as part of the ongoing negotiations between Iran and the P5+1 group -- the US, Britain, France, Russia, China, plus Germany, Xinhua reported on Tuesday.
The two sides are aiming for a comprehensive agreement over Iran's controversial nuclear programme by the end of June, as they have failed to meet two self-imposed deadlines over the past year.
