Iran’s Supreme Leader Ali Khamenei said on Sunday that the country will keep advancing its nuclear program, pushing back against renewed US demands to restrict uranium enrichment. His comments signal continued defiance as tensions remain high over Iran’s nuclear activities and Western efforts to limit them.

The remarks come amid long-running disputes between Tehran and Washington over enrichment levels, inspections, and sanctions. US officials have repeatedly said they want tighter limits on Iran’s program, while Iranian authorities have insisted their nuclear work is lawful and must continue.

Khamenei’s statement is likely to deepen concerns among diplomats tracking the stalled nuclear standoff. For civilians in Iran, the ongoing confrontation has carried a heavy cost, with sanctions and isolation worsening economic pressure while the government continues to prioritize its nuclear agenda.

The latest comments add to an already fragile regional picture, with no clear sign of a breakthrough in talks. As pressure builds, the gap between US demands and Iran’s position remains wide.
