The trigger: a ban imposed by the Iran-aligned Huthi rebels, who control the capital Sanaa and most of the country's north, on using new banknotes printed by the central bank in Aden. The southern port city became the seat of the internationally recognised government after it was driven out of Sanaa in 2014.
