SANAA, Yemen — Yemeni military officials say hundreds of troops and dozens of tanks and armored personnel carriers are pushing north toward the al-Anad military base in Yemen, as Saudi-led coalition airstrikes clear the path for their advance.
The officials said allied fighters have gained control of the western gate of the key base.
Houthi officials say the base remains under rebel control amid fierce fighting and continuous Saudi-led coalition airstrikes.
Al-Anad, once the site of U.S. intelligence operations against al-Qaida's powerful Yemeni affiliate, is the main rebel encampment in the country's south.
Military officials said soldiers and allied pro-government forces are also reinforcing the front in the strategic southern city of Zanjibar, west of Aden.
All officials spoke on condition of anonymity because they were not authorized to speak to reporters.
