The United States has carried out a fresh round of strikes on Iran after Iranian forces hit a civilian cargo vessel in the Strait of Hormuz. The latest escalation comes despite a fragile ceasefire and raises fresh concerns over the security of one of the world's most critical shipping lanes.

A Cyprus-flagged container ship struck by Iran suffered “significant engineroom damage” and a civilian crew member is missing, U.S. Central Command said.

Iran's Islamic Revolutionary Guard said the strait was 'closed until further notice and until regional interference by the US ceases.'
