Ayatollah Khamenei Says Iran Will Not Step Back From Its Nuclear Rights
Negotiations on Iran's nuclear program taking place in Geneva
Iran's Supreme Leader has warned his country will not step back "one iota" from its nuclear rights, as it resumes talks with world powers in Geneva.
Ayatollah Ali Khamenei said he would not intervene directly in the negotiations, but that he had set "red lines" for Iran's representatives.
President Barack Obama meanwhile urged US senators not to impose new sanctions on Iran to allow time for diplomacy.
He was unsure if it would be possible to reach an interim agreement soon.
