Iran nuclear talks thrown into disarray by Natanz attack

Iran’s supreme leader Ayatollah Khamenei has dismissed the latest overtures aimed at saving the nuclear deal between Iran and major world powers as “not worth looking at”.

Informal discussions on the deal are underway in Vienna, but plans to move into more formal talks have been thrown into disarray by the attack on Iran’s nuclear facility in Natanz over the weekend.

Tehran has responded by saying it will dramatically step up its uranium enrichment activities.
