US, UK Navies Rush to Aid Ship Harassed by Iranian Forces in Strait of Hormuz

US and UK navies came to the aid of a merchant ship after it was approached by Iranian Revolutionary Guard vessels.
Three armed fast-attack craft approached the merchant ship at close distance before departing an hour later.
The US and UK navies launched a helicopter and destroyer in response to deter further aggression.
The Strait of Hormuz is crucial to global oil supplies, with 20% of the world's oil passing through it.
Tensions have been high between Iran and Western powers since the US withdrew from the Iran nuclear deal in 2018.
