The fourth round of Iran-US nuclear negotiations in Muscat, Oman dominated Iranian media. Early morning headlines showed FM Araqchi departing for talks after declaring uranium enrichment "non-negotiable" - a position reinforced throughout the day with statements that "the blood of our nuclear scientists" had been spilled for this capability.

The three-hour talks concluded by mid-afternoon, with both sides expressing cautious optimism. Araqchi characterized the negotiations as "more serious and direct" than previous rounds, noting positions had moved "slightly closer together." An unnamed American official described the talks as "encouraging" while emphasizing US demands remained unchanged.

Oman will announce the timing for a fifth round. President Pezeshkian reinforced Iran's position, stating "abandoning nuclear facilities is unacceptable" while affirming Iran seeks serious negotiations. Military chief Bagheri simultaneously declared Iran's armed forces "fully prepared for any situation."
