Yemeni officials say Shiite rebels and their allies have seized another part of the southern port city of Aden after heavy fighting with militiamen loyal to the exiled government.

Military officials say rebels known as Houthis took Aden's southwestern Tawahi district, killing the area's military commander, Maj. Gen. Ali Nasser al-Hassani, in the process.

Meanwhile, security officials say Saudi-led airstrikes continued to pound the rebels, striking targets in Aden as well as the cities of Marib, Saada, and Dhamar. Dozens of rebels and their allies were killed there.

There was also fighting Wednesday in Marib province, and aircraft also struck the Anad air base north of Aden, once the site of U.S. intelligence operations.

All officials spoke on condition of anonymity because they weren't allowed to brief journalists.
