Saudi-led airstrikes killed 15 people and wounded dozens across Yemen late on Saturday, the Houthi-run Saba news agency reported.

The dead included five women and two children in attacks on Saada and Marib provinces, the agency said.

A Saudi-led Arab coalition has been bombarding Houthi rebels and allied army units since 26 March in a campaign to restore President Abd-Rabbu Mansour Hadi to power.

Hadi, Saudi Arabia’s ally, was pushed aside last year when Houthis advancing from their northern strongholds overran the government in the capital, Sana’a, and went on to capture lands to the south.

The Houthis are allied to former president Ali Abdullah Saleh, who still has the loyalty of much of the army.

UN-sponsored talks in Geneva between Yemen’s warring parties ended on Friday without agreement on a ceasefire, an outcome relief agencies had sought in order to support efforts to stave off what many see as a humanitarian disaster.

More than 2,800 people have been killed since 26 March. The United Nations says more than 21 million people, or 80% of the population, need some form of humanitarian aid, protection or both.

A series of co-ordinated bombings claimed by Islamic State has added another layer to the conflict. In the latest, Isis said it was behind a car bomb that exploded in Sana’a on Saturday near the Qiba al-Mahdi mosque, killing two people and wounding six.

Isis regards the Houthis, a political movement hailing from the Zaydi sect of Shia Islam, as apostates.
