Salm also led raids into the Khwarazm. However, his deputies in Sijistan and Zabulistan, the latter was under the command of his brother Abu Ubayda, were not able to emulate Salm's successes in the region that corresponds with modern-day Afghanistan. There, the Zunbils of Zabulistan and the shahs of Kabul put up stiff resistance against the Arabs, and Yazid and Abu Ubayda were ultimately slain and captured, respectively, during military expeditions against them.
