US Official: 'Drafting of deal with Iran began in May'

"... "Actually there was some drafting... at the last round," the official said. "A little bit of that was done the last time, and it was expected more will take place during this round." While stressing that "significant" differences remain, the official indicated that progress was made at bilateral talks between the United States and Iran in Geneva last Monday and Tuesday.
"We not only understood each other better after those two days but I think we both can see places where we might be able to close the gaps," the official said...."
