The Strait of Hormuz is a narrow body of water adjacent to Iran and Oman, which connects the Persian Gulf to the Gulf of Oman.
While it is a shared body of water between Iran and Oman, Iran functionally exercises a greater amount of control over it.
The strait is a vital conduit for the shipment of oil, gas and other exports (notably fertiliser) from the Persian Gulf to the rest of the world. At its narrowest point, it is just 21 nautical miles (24 miles or 39 kilometres) wide.
