Iran’s Supreme Leader Ayatollah Ali Khamenei rejected a US proposal to end uranium enrichment, calling it “100 percent against the country’s interests.”
Oman is mediating the proposal, which calls on Iran to export its uranium stockpile and stop enrichment. Khamenei criticized American demands as boastful and maintained that enrichment is essential to Iran's nuclear program and national independence, according to Al Jazeera.
Major differences have not been resolved despite ongoing talks.
