As fighting in the Middle East entered its third week, focus has shifted to Tehran’s closure of a key maritime passage, and the potentially huge global economic impact.

For our big story this week, Jillian Ambrose explains how the war in Iran has effectively blocked the Gulf states from exporting a fifth of the world’s oil supply through the strait of Hormuz. Peter Beaumont sets out the significance of the route and the possible options to counter the blockade, while Hannah Ellis-Petersen reports on the building anger and resentment in the region over being dragged into a war they did not start and had diplomatically tried to prevent.

Peter also looks at “the escalation trap” that lies ahead for both sides in the conflict, and we have on-the-ground reports from Jason Burke in northern Israel and William Christou in southern Lebanon, as well as a stark account of day-to-day life from inside Tehran.

The mooring of the Bibby Stockholm barge in Portland, England, UK, to provide shelter for vulnerable asylum seekers sparked outrage from both sides of the political spectrum back in 2023. Negative stories dominated the headlines but a new photo exhibition in London – about a group of locals that formed a welcome party – reveals a different, softer side to the story. A perfect antidote to the negative news cycle. Emily Elnusairi, deputy production editor
