Fresh threats around the Strait of Hormuz added pressure to a fragile U.S.-Iran diplomatic track after Iran's Islamic Revolutionary Guard Corps said ceasefire violations would breach the Islamabad accord, stop all ongoing processes and could prompt tougher measures against vessels in the waterway. The warning came as U.S. Central Command said it struck multiple Iranian targets again, Donald Trump warned Iran could cease to exist if the U.S. completes military action, and UKMTO reported another tanker struck in the strait. Bahrain also condemned an Iranian drone attack, while separate reporting said U.S. forces shot down nine drones. The renewed escalation reinforced instability around a key global oil chokepoint despite earlier signs of de-escalation, maritime safeguards and reported resumed talks.
