The simmering tensions between the United States and Iran have erupted into a fresh cycle of violence, as Washington launches its eleventh consecutive night of military strikes against the Islamic Republic's strategic targets. The latest salvo, confirmed by US Central Command (Centcom), aims to curb Tehran's ability to menace commercial shipping in the vital Strait of Hormuz.
Iranian state media reported explosions in multiple cities, including Tabriz and Bushehr – home to its sole nuclear power plant – after air defences were activated in the capital, Tehran. Centcom stated that US forces struck Iranian military operations centres, maritime capabilities, aircraft hangars, drone storage facilities, and logistics infrastructure. The US has accused Iran of attacking over 30 commercial vessels in the Strait of Hormuz since May, putting seafarers at risk and undermining freedom of navigation.
The escalation comes as President Donald Trump issued a stark warning that the US would soon target an underground nuclear site near Natanz, known as Pickaxe Mountain. This facility is suspected of housing an undeclared enrichment programme. Speaking alongside Lebanese President Joseph Aoun, Trump declared, "We'll be hitting that area pretty soon, and very heavily." Iran's Khatam Al-Anbiya military command has vowed to retaliate against "all the interests of America, its allies and supporters" if such a strike occurs.
The regional security landscape is further complicated by threats from Iranian-backed Houthi rebels in Yemen. The group has warned that it will block Saudi ports, including closing the Bab al-Mandab Strait – the Red Sea's southern gateway – to Saudi vessels. This threat has already prompted two tankers carrying Saudi crude for China and India to reroute through the Suez Canal. The Red Sea has become a critical route for Saudi oil shipments following the closure of the Strait of Hormuz due to hostilities between the US, Israel, and Iran.
The current escalation represents a breakdown of a ceasefire agreed between Iran and the US in April and a subsequent Memorandum of Understanding signed in June aimed at halting military operations and reopening the Strait of Hormuz. President Trump declared the June ceasefire "over" just three weeks after its signing, citing renewed Iranian attacks on ships. The conflict has taken a significant financial toll on the US, with Defence Secretary Pete Hegseth informing the Senate Appropriations Committee that the war has cost approximately $37.5 billion (£28 billion) to date, an increase of nearly $8 billion since May.
