Saudi airstrikes in Yemen's capital kill 29

The coalition's airstrikes hit an apartment building in the center of the capital, a UNESCO world heritage site, killing a family of nine, the officials who remain neutral in the conflict that has divided Yemen's security forces said.

One more civilian was killed and the search for more that may be buried under rubble is ongoing. The rebels, known as Houthis, lost 19 fighters in the overnight attack, the officials said.

The Houthis still control the capital and are resisting a push by pro-government forces along several frontlines around the country.

Yemen has been torn by a ferocious war pitting the Houthis and forces fighting for former President Ali Abdullah Saleh against Hadi loyalists, as well as southern separatists, local militias and Sunni extremists.

The conflict escalated in March as a Saudi-led coalition launched airstrikes against the Houthis.

Saudi-led coalition planes have targeted Houthi strongholds with greater intensity since a Houthi-led attacked killed dozens of Arab coalition forces last Friday.

Yemen is torn between the Houthis, allied with army units that have pledged allegiance to Saleh, and forces loyal to exiled President Abed Rabbo Mansour Hadi.

The conflict has killed over 2,100 civilians, according to the United Nations.

The developments came as Shiite rebels known as Houthis launched new attacks, after weeks of retreating as pro-government troops pushed north out of Aden. Yemen's fighting, which escalated in March, pits the Houthis and troops loyal to former President Ali Abdullah Saleh against southern separatists, local and tribal militias, Sunni Islamic militants and troops loyal to President Abed Rabbo Mansour Hadi.

Meanwhile, Yemen's pro-government troops fought pockets of resistance outside a key military base in the country's south, a day after they seized it from Shiite rebels, military officials said.

The capture of the Al-Anad base - once the site of US intelligence operations against al-Qaida's powerful Yemeni affiliate - was a significant victory for the forces allied to Yemen's exiled President Abed Rabbo Mansour Hadi in their battle to reverse the gains of the rebels known as Houthis.
