US-Israel-Iran War Live News Updates: US State Department Issues 'Worldwide Caution' Memo; Strait Of Hormuz Is Not Closed, Araghchi Says

Lebanese President Joseph Aoun has condemned Israel's recent attacks on critical infrastructure, calling them "collective punishment" on Lebanese civilians. The strikes have displaced an estimated one million people, making it challenging for the government and humanitarian organizations to provide aid, especially in southern Lebanon. Aoun believes Israel's actions, including targeting bridges and infrastructure, are an attempt to create a de facto buffer zone and may be a precursor to a wider ground invasion, reports Al Jazeera.

Iran has reportedly limited its attacks on Saudi Arabia due to concerns that continued strikes could trigger a direct military response from Saudi Arabia. Since the war began, Iran has launched over 430 missiles and drones targeting Saudi Arabia, focusing on oil refineries in the Eastern Province and Prince Sultan Air Base in Al-Kharj, two sources told The Jerusalem Post.

The Prime Minister of the United Kingdom spoke to the President of the United States, Donald Trump and discussed the current situation in the Middle East, and in particular, the need to reopen the Strait of Hormuz to resume global shipping. They agreed that reopening the Strait of Hormuz was essential to ensure stability in the global energy market. They agreed to speak again soon, UK government said.

Iran's Parliament Speaker, Mohammad Bagher Ghalibaf, has warned that financial institutions financing the US military budget are legitimate targets, alongside military bases.

In a post on X, he wrote, "Alongside military bases, those financial entities that finance the US military budget are legitimate targets. US treasury bonds are soaked in Iranians' blood. Purchase them, and you purchase a strike on your HQ and assets. We monitor your portfolios. This is your final notice."

The Department of State advises Americans worldwide, and especially in the Middle East, to exercise increased caution.  Americans abroad should follow the guidance in security alerts issued by the nearest U.S. embassy or consulate.  Periodic airspace closures may cause travel disruptions.  U.S. diplomatic facilities, including outside the Middle East, have been targeted.  Groups supportive of Iran may target other U.S. interests overseas or locations associated with the United States and/or Americans throughout the world.

The war, which the US and Israel launched February 28, has killed over 2,000 people. Here are some overnight developments that took place.
