US Secretary of State John Kerry underlined on Thursday night that both Iran and the six major world powers are resolved to continue the nuclear negotiations based on the Lausanne statement to cut a final deal before July 1 deadline.

 Kerry tweeted that all sides have the "parameters to resolve major issues" on Iran's nuclear program and will soon get back to work on a "final deal."

"Big day," he further tweeted.

Also, Iran's President Hassan Rouhani minutes ago voiced satisfaction in the outcomes of the latest round of talks between Tehran and the Group 5+1 (the five permanent UN Security Council members plus Germany) in the Swiss city of Lausanne.

"Solutions on key parameters of Iran nuclear case reached," President Rouhani wrote in a new post on his Tweeter page.

"Drafting (of the final deal) will start immediately to finish by June 30th," he added.

Iran and G5+1 started their new round of talks in Lausanne, Switzerland, last Thursday to narrow their differences over Tehran's nuclear energy program ahead of a July 1 deadline.
