The Houthi siege of Yemen's Taiz city may constitute a war crime of using starvation as a weapon of war, leading to a roughly 400% increase in cooking gas prices, Human Rights Watch (HRW) said. The organization stated that the Houthis are depriving civilians in the besieged Yemeni city of Taiz of food, water, and medicine. The humanitarian crisis in Yemen's third-largest city has sharply deteriorated since the Houthis fully encircled the city and blocked the last main supply line in October. Laurent Bukera, the UN Humanitarian Coordinator for Yemen, said the city's health system is "on the verge of collapse."
