Iranian Foreign Minister Abbas Araghchi said Sunday that nuclear talks with the US in Oman have grown "more serious and frank," with discussions focusing on concrete suggestions. The most recent discussion lasted three hours, and both sides agreed to continue negotiations, according to Xinhua.

President Masoud Pezeshkian dismissed US efforts to remove Iran's nuclear facilities as "unacceptable." He underlined Iran's right to peaceful nuclear technology, citing potential applications in healthcare and industry.

US authorities continue to push for the demolition of Iran's key nuclear sites, despite Iran's insistence that its program is entirely civilian and non-military, Xinhua reported.
