Tehran has warned it will launch an offensive in the Strait of Hormuz if ongoing diplomatic negotiations with the United States do not yield a resolution.
The threat comes as the US-Iran Memorandum of Understanding expires, with Iran rejecting any interim deal extensions and signaling potential escalation.
Global oil markets have reacted to the instability, with Brent crude prices rising above $90 per barrel amid fears of disrupted shipping through the critical waterway.
