US and UK naval forces intervene to stop Iranian boats harassing merchant vessel in Strait of Hormuz.

US and UK naval ships intervened to protect a merchant vessel from being "harassed" by Iran's Revolutionary Guard in the Strait of Hormuz. The incident involved three Iranian "fast-attack" vessels armed with troops approaching the merchant ship. The US Navy's USS McFaul and the UK Royal Navy's HMS Lancaster responded to the scene, and the situation deescalated an hour later when the merchant vessel confirmed the fast-attack craft had departed. The Strait of Hormuz is a major international trade route, and Iran has been looking to take advantage of it as relations with the US have deteriorated.
