Vienna, May 15 (IANS) Iranian nuclear talks entered the second day Thursday amid low expectations of a breakthrough that could resolve a decade-long dispute over Tehran's nuclear programme. Iran and the five permanent members of the United Nation Security Council (Britain, China, France, Russia, United States) plus Germany, have started drafting a deal to pave the way for a final agreement by July 20, Xinhua reported. A US State Department official said Thursday \"coordination and experts' meetings will resume and continue throughout the day.\" Michael Mann, spokesperson of European Union foreign policy chief Catherine Ashton, said she held a bilateral meeting with Iranian Foreign Minister Mohammad Javad Zarif. Western states want Iran to significantly scale back its nuclear programme, especially its nuclear fuel production capability.
