Mojtaba Khamenei on Thursday said Iran will protect its nuclear and missile capabilities as “national assets,” signalling a hardening stance amid tensions with the United States over the ongoing conflict and fragile ceasefire.

In a written statement aired on state television, Khamenei struck a defiant tone, warning that foreign powers—particularly the US—have no place in the Persian Gulf, and declaring that a “new chapter” is unfolding in the region.

His remarks come as Donald Trump pushes for a broader agreement with Tehran, while a US naval blockade continues to restrict Iran’s oil exports, intensifying economic pressure.

Global energy markets have reacted sharply, with Brent crude prices surging as Iran maintains control over the Strait of Hormuz—a vital route through which a significant portion of the world’s oil and gas supplies pass.

Khamenei indicated that Iran’s nuclear programme and ballistic missile capabilities are non-negotiable, describing them as integral to national sovereignty and security.

He also suggested that Tehran would continue asserting control over the strategic waterway, arguing that its management would enhance regional security—claims strongly rejected by Gulf nations, who view such actions as a threat to international shipping.

The developments add to mounting global concerns over energy security and the risk of further escalation in the region, even as ceasefire efforts remain in place.
