The coordinated assault targeted civilian infrastructure across four south-western cities, including the city of Abha, where satellite imagery showed smoke rising from a Saudi Aramco bulk plant. Fires broke out at oil facilities and installations, forcing a temporary halt in operations, according to the Saudi military and energy ministry.
Major General Turki al-Maliki, spokesman for the Saudi-led coalition, stated that the Houthi attacks deliberately targeted civilian and economic sites. The coalition's forces are preparing a response to the escalation.
The Houthi movement claimed the operation was in retaliation for what they described as dozens of recent Saudi strikes on north-western Yemen. On Monday, the Houthis accused Saudi Arabia of bombing a prison in the city of al-Hazm, killing at least 11 people, with a further 20 inmates reportedly missing under the rubble.
The attack follows a series of escalating incidents in the region. In August, the Houthis reportedly killed six people in their first deadly attack since the start of the Iran war, and earlier that month they reportedly killed at least 30 Yemeni government forces.
