A military flare-up between Yemen's Iran-backed Houthi rebels and Saudi Arabia is challenging the relative calm in the war-torn country, with the two sides on the brink of renewed conflict. The escalation endangers the fragile stability that had taken hold and raises the possibility that Yemen could be drawn into a wider Middle East war. Riyadh and the Houthis are reportedly close to resuming hostilities, threatening to plunge the nation back into full-scale conflict. The situation underscores how quickly regional tensions can spill over, as Yemen, already devastated by years of war, faces the risk of becoming a new front in a broader confrontation.
