Iranian negotiator says nuclear deal `doable`, `two or three` issues remain

A nuclear deal between Iran and world powers is "doable" with "two or three" issues left to resolve, Tehran`s lead negotiator said in crunch talks in Switzerland.

"Getting to an accord is doable. Solutions have been found for numerous questions. We are still working on two or three issues... The talks are in their final phase and are very difficult," Abbas Araqchi told reporters in Lausanne.
