WorldYemen’s Houthis and Iran: How deep is their alliance?

Analysts trace the group to a 1990s Zaydi revival, saying it has links to Iran while retaining independent Yemeni roots. UN experts have documented support from Iran’s Revolutionary Guards and Hezbollah, although Tehran denies arming the Houthis.
