UK bans Iran's Revolutionary Guards, Trump reimposes US blockade

On July 13, 2026, the United Kingdom proscribed Iran's Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization, blaming an IRGC-backed group for attacks on Jews. Separately, President Donald Trump announced he is reimposing the US blockade of Iran, causing oil prices to jump and the Nasdaq to slump. The UK ban makes it illegal to support or be a member of the IRGC. These actions mark a significant escalation in international pressure on Iran.
