Smoke rose from a training camp used by Yemeni government forces after an attack by the Houthis. The Houthis control much of northern Yemen and have fought the internationally recognized government since 2014. Strikes on military facilities, including bases where recruits are prepared, have recurred throughout the war. A training camp concentrates soldiers and instructors in one place, which makes it an appealing target for an attack. No casualty figures were immediately confirmed. The incident points to a front that stays dangerous even when the wider conflict draws less attention.
