US-Iran nuclear talks advance via Pakistan

A senior Iranian official has told Reuters that significant gaps remain in negotiations with the United States, facilitated by Pakistan. The unresolved issues specifically concern the fate of Iran's enriched uranium stockpile and the duration of restrictions to be imposed on its nuclear program. This statement injects a note of caution into the diplomatic process, which had recently seen reports of progress. The talks continue as the US maintains a naval blockade on Iran.
