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.
The Houthis are allied to former president Ali Abdullah Saleh, who still has the loyalty of much of the army.
More than 2,800 people have been killed since March 26. The United Nations says more than 21 million people, or 80 percent of the population, are now estimated to be in need of some form of humanitarian aid, or protection, or both.
A series of coordinated bombings claimed by Islamic State has adding another layer to the conflict.
In the latest, Islamic State said it was behind a car bomb that exploded in Yemen’s capital Sanaa on Saturday near the Qiba al-Mahdi mosque, killing two people and wounding six.
Islamic State consider the Houthis, a political movement hailing from the Zaydi sect of Shi’ite Islam, as apostates.
