HELSINGBORG, Sweden, May 22 (Reuters) - The United States has seen some progress in talks with Iran and is in constant communication with the Pakistani mediators, but there is more work to be done, Secretary of State Marco Rubio said on Friday.
"There's been some progress. I wouldn't exaggerate it. I wouldn't diminish it," Rubio told reporters after a NATO ministers meeting in Sweden.
"There's more work to be done," he added. "We're not there yet. I hope we get there."
