The Strait of Hormuz - The Strait of Hormuz, also called Strait of Ormuz, is a strait, or narrow channel, linking the Persian Gulf (west) with the Gulf of Oman and the Arabian Sea (southeast).

Gulf State corridor - The strait is about 167 km (90 nautical miles) long, with a width varying from about 96 km (52 nautical miles) to 39 km (21 nautical miles). On the north coast lies Iran (pictured), and on the south coast the United Arab Emirates and Musandam, an exclave of Oman.

Strategic waterway - The strait is of great strategic and economic importance. It provides the only sea passage from the Persian Gulf to the open ocean, and a third of the world’s liquefied natural gas and almost 20% of the total global oil consumption passes through this narrow waterway.

Shipping lanes - Ships moving through the strait follow what's known as a maritime traffic-management route-system: inbound ships use one lane, outbound ships another, each lane being two miles wide. The lanes are separated by a two-mile-wide "median," or clear sea zone.

Disputed islands, disputed waters - Located within this "median" are three islands—Tunb as Sughra, Tunb al Kubra, and Abu Musa. While each is occupied by Iran, the United Arab Emirates also lays claim to the islands.

Oil exports threatened - In April 2019, the United States ended sanctions exemptions, effectively banning all Iranian oil exports. Iran hit back, threatening that if its oil exports are stopped, then no oil can pass the Strait of Hormuz. Pictured: Iranian military patrol the region.

"Sabotage" - United Arab Emirates officials reported that the ships—which included two Saudi oil tankers—had been subject to a "sabotage attack." Amid increasing tensions between the United States and Iran, US officials accused Iran of being behind the attack.

Gulf of Oman incident - One month later the US again blamed Iran for the attacks on two oil tankers, the Norwegian Front Altair and the Japanese Kokuka Courageous (pictured), near the Strait of Hormuz. Limpet mines were allegedly used to damage the hulls resulting in fire damaged.

MV M. Star - Attacks on shipping in the region is nothing new. In July 2010, Japanese oil tanker the MV M. Star was damaged by an explosion believed to have been caused by a terrorist attack in the Strait of Hormuz. Radar had pinpointed a suspicious craft near the vessel just before it was attacked, and traces of explosives were subsequently found on the hull. In the 1980s the Persian Gulf was the scene of the so-called "Tanker War."

US 5th Fleet in Strait of Hormuz -

HMS Montrose -

In July of the same year, the Royal Navy warship HMS Montrose was forced to intervene when Iranian gunboats tried to disrupt the passage of the commercial ship British Heritage. The ship was in disputed waters claimed by Iran when it was challenged by the Iranian vessels and ordered to move north. The British warship trained its guns on the approaching vessels to fend them off.

Iranian drone downed - Tensions in the Strait of Hormuz then increased with the shooting down of an Iranian aerial drone on July 18 by the amphibious assault ship USS Boxer (pictured). The standoff between Iran and the United States increased threats to Gulf shipping as both sides accused the other of "provocative and hostile" behavior.

Seizure of the Stena Impero - A boat of the Iranian Revolutionary Guard sails next to Stena Impero, a British-flagged vessel that was subsequently seized in the Strait of Hormuz on July 20, 2019, and docked at the Port of Bandar Abbas, Iran, for two months. It was believed to be an act of retaliation for Britain's assistance in seizing an Iranian tanker off the coast of Gibraltar two weeks earlier.

The effect on tourism - It wasn't only oil tankers that were caught up in the crisis. The Strait of Hormuz is the gateway to the Persian Gulf, a popular destination for cruise ships from around the world. Pictured: a liner at the port of Khasab, in Oman.
