The Strait of Hormuz is a narrow gap of water in the Middle East between Iran and the Arabian peninsula. About 3,000 or so ships sail through the Strait each month - that’s about 80 ships a day. About 20% of the world’s oil and gas passes through it. But now, it’s an active war zone.

As the US and Israel continue strikes on Iran, and Iran launches missiles at Israel and nearby Gulf states in retaliation, key shipping routes are being disrupted as well as oil and gas production in the region.

Iran says it has complete control of the Strait of Hormuz, and that it would "set fire" to any ships trying to pass through it.

In this episode we explain how this war could affect the wider world and why closing the Strait of Hormuz could lead to higher prices for petrol, food and electronics for us all.

Kayleen Devlin from BBC Verify tells us what’s happening to ships in the Strait of Hormuz and BBC business reporter Nick Marsh describes why parts of Asia are already feeling the effects.
