What happened

BBC News reports: Why and how is US blockading Iranian ports in Strait of Hormuz?.

Why it matters

Oil prices have risen to their highest since 2022, following reports that US President Donald Trump is to be briefed by his military on plans for further strikes on Iran.

Common ground

Brent crude's rise to more than $126 (£94) a barrel, before falling back, continues an upward trend in energy prices as peace talks between the US and Iran appeared to have stalled.

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
