"This report provides information on the ongoing crisis in Yemen. Now in its fourth year, the war in Yemen shows no signs of abating and may be escalating. In recent weeks, the northern Yemeni armed militia and political movement known as the Houthis have launched several missile attacks into Saudi Arabia, while the Saudi-led coalition, a multinational grouping of armed forces primarily led by Saudi Arabia and the United Arab Emirates (UAE), has continued to conduct air strikes inside Yemen. Including combatants, the war in Yemen may have killed more than 10,000 Yemenis and has significantly damaged the country's infrastructure. As the war continues, the risk of it spreading beyond Yemeni territory appears to be growing."
