Only two vessels not linked to Iran or Russia have braved ‘chicken run’ since US president’s promise on Friday

Middle East crisis – live updates

Only two vessels not linked to Iran or Russia have made the “chicken run” through the strait of Hormuz since Donald Trump said he would “ensure the free flow of energy to the world”, according to maritime records.

One of those that braved the journey since the US president’s announcement of emergency measures on Friday went “dark” by switching off its transponder and a second signalled it was Chinese owned and crewed.

The Hormuz sea passage, one of the world’s most strategically important choke points, would normally have about 100 vessels a day either exiting or entering the Gulf. In response to the US and Israeli attacks, Iran has effectively shut the strait, attacking at least 10 ships which were seeking to traverse it in the early days of the crisis.
