Iran Issues Strait of Hormuz Transit Warning, Threatens Retaliation Over US Sanctions

Iran's Persian Gulf Strait Authority has warned vessels in the Strait of Hormuz about potential fines, detention, or confiscation for non-compliance with transit rules. Concurrently, Iran vowed "seismic" retaliation against any nation cooperating with new US economic sanctions, threatening to block oil exports from the Persian Gulf if regional states support the US. This escalates geopolitical tensions and poses risks to global shipping and energy markets.
