Nuclear deal

Talks have resumed in Switzerland ahead of Tuesday's deadline for a preliminary nuclear deal with Iran. Foreign ministers from six world powers are meeting their Iranian counterpart, amid hopes of a breakthrough after almost 18 months of negotiations. They want to impose limits that would prevent Iran from producing enough fuel for a nuclear weapon within a year. Iran, which insists its nuclear programme is peaceful, wants to see crippling sanctions lifted in return. Iranian and Western officials have said that a deal is possible, but that some issues are still to be resolved. The negotiations in Lausanne were expected to intensify on Monday, with foreign ministers from the so-called P5+1 - comprising the US, UK, France, China, Russia and Germany - meeting Iran's Mohammad Javad Zarif. The EU foreign policy chief Federica Mogherini is also there.
