Houthis strike Saudi oil facilities; Yemen ceasefire collapses, 20k displaced

A four-year ceasefire between Houthi rebels and Saudi-backed Yemeni forces has collapsed. Houthis launched dozens of missiles and drones at Saudi oil facilities, prompting Saudi airstrikes; government forces report liberating areas, with nearly 20,000 displaced. The escalation marks a major reversal of the truce and threatens regional energy infrastructure.
