Iran closes the Strait of Hormuz, the international lifeline where approximately 20% of the world's oil and liquefied gas is transited.

The Iranian Parliament on June 22 approved a groundbreaking resolution allowing the closure of the Strait of Hormuz – a strategic shipping route transporting nearly 1/5 of global oil production "when necessary" in response to U.S. airstrikes on a series of Iranian nuclear facilities on June 21.

Speaking before Parliament, Iranian lawmakers asserted that closing Hormuz is a "sovereignty defense action" and a "mandatory option if the U.S. continues to escalate." The resolution received near-unanimous support from members, amidst heightened tensions between the two nations following the military campaign "Midnight Hammer" launched by Washington.

General Esmail Kosari – a member of the Islamic Revolutionary Guard Corps (IRGC) and a parliament member – stated: "Iran has the full right to decide to use Hormuz as a deterrent. If necessary, this strait will be closed immediately."

However, the final decision on implementation rests with the Supreme National Security Council, the highest authority in Iran's political system, under the direction of Supreme Leader Ayatollah Ali Khamenei.
