Iran and the US have traded strikes as hostilities re-escalated this week, with Tehran targeting US military facilities across the Gulf region.

Two US service members were killed and one remains missing after Iranian ballistic missile and drone attacks in Jordan on Friday, military officials said. The US Central Command (Centcom) said four US service members were medically evacuated to Jordan hospitals but have since been discharged. Others who had minor injuries have returned to duty. US military officials did not disclose the identities of those killed, nor provide details about the circumstances or location of the incident. On Saturday night the US launched another round of air strikes against Iran at President Donald Trump's direction, Centcom said. The strikes - for the eighth night in a row - are "designed to further degrade Iran's ability to threaten commercial shipping in the Strait of Hormuz", the statement said. The strikes aim to "swiftly punish Islamic Revolutionary Guard Corps forces who launched attacks against American service members in Jordan last night," the statement continued, without providing further details. It followed a week of renewed hostilities in which Washington reimposed its blockade of Iranian ports and Tehran declared the Strait of Hormuz closed, as their preliminary ceasefire collapsed less than a month after it began. Late on Saturday, Iran's Supreme Leader Mojtaba Khamenei said in a written statement that America's "repeated breaches" of the agreement had "laid bare a fundamental truth: the signature of the US president is utterly worthless and devoid of credibility".
