The US has attacked Iranian targets after Tehran struck a cargo ship in the Strait of Hormuz, in a spat which threatens to topple the fragile ceasefire agreement.

American aircraft struck Iranian missile and drone storage locations, as well as coastal radar sites, according to US Central Command (CENTCOM). Iranian naval forces responded by striking US military targets in the region, though it is not yet clear what was hit.

It came after Iran launched a drone attack on a Singaporian cargo ship as it passed through the Strait of Hormuz, CENTCOM said.

The Strait is a key international shipping lane through which around 20 per cent of the world’s oil and gas transits, and has been an important bargaining chip for Iran in the war which began in late February. Tehran effectively closed the waterway to exert pressure on the US by causing a spike in energy prices worldwide.
