Live fire near the Strait of Hormuz overnight has again demonstrated the fragility of a ceasefire between Iran and the United States.

Iran launched missile strikes overnight, hitting oil production facilities in the United Arab Emirates as well as an an Emirati tanker. Several civilians were left injured.

The US military says it fired on Iranian forces and sank six small boats targeting civilian ships as it moves to reopen the Strait of Hormuz.

The US military also says it has successfully escorted two American-flagged merchant ships through the Strait.
