Washington and Tehran may sign a preliminary agreement to reduce the level of uranium enrichment in Iran, the Saudi Al Arabiya television channel quoted sources.
"Washington [as part of a future deal] allowed uranium enrichment in Iran to a level of 3.67%, and Tehran agreed," the channel quoted the sources as saying.
At the same time, the US demands a reduction in uranium enrichment, which has already been enriched to 60%. For these purposes, the parties also discuss the involvement of a third country.
