Saudi Arabia has said it has struck more than 40 Yemenis in the capital Sanaa, including women and children, as part of a campaign to drive back Houthi rebels.
The kingdom has blamed Iran-allied Houthi fighters for the attacks, but the United Nations said on Friday it was “surprised and alarmed” at the airstrikes.
Saudi Arabia said the strikes had targeted a “terrorist base” that had targeted its allies in Yemen.
It said it targeted fighters from the “Houthi Ansarullah movement” which has been fighting to topple Yemen’s president, Abd Rabbuh Mansour Hadi.
It also said it killed more than 30 fighters and wounded others in the attacks on Saturday and Sunday.
Yemen’s warring sides have been fighting for more than six years, as a coalition of countries and Iran-backed rebels and tribes have fought a devastating war for control of the impoverished country.
In January, the Saudi-backed government launched air raids on Houthi positions, killing hundreds of civilians.
The Saudi-controlled warplanes have since targeted the rebels and the Houthi forces, who have fired missiles and other weapons at Riyadh.
The Saudi-allies have also carried out raids on the southern port city of Aden, which has remained under Houthi control since 2014.
