Iranian foreign ministry spokesman Esmaeil Baqaei says the "peaceful use of nuclear energy is a right of the Iranian nation" during his weekly press conference in Tehran. US Secretary of State Marco Rubio in an interview with Fox News called on Iran to "walk away" from uranium enrichment, saying "the only countries in the world that enrich uranium are the ones that have nuclear weapons". Tehran denies seeking to acquire nuclear weapons, insisting that its nuclear ambitions are entirely peaceful and for civilian purposes. IMAGES AND SOUNDBITES
