STOCKHOLM, May 22. /TASS/. The US administration is seeing "slight progress" in negotiations regarding the situation around Iran, US Secretary of State Marco Rubio said in the Swedish city of Helsingborg, which is hosting a meeting of NATO foreign ministers.

"There’s been some slight progress, I don’t want to exaggerate it, but there’s been a little bit of movement, and that’s good. The fundamentals remain the same. Iran can never have a nuclear weapon, it just cannot," Rubio pointed out, speaking after talks with NATO Secretary General Mark Rutte. He noted that Tehran "can never have nuclear weapons." "To achieve that, we're going to have to address the issue of enrichment," Rubio specified.
