An air strike has hit a hospital run by Medecins Sans Frontieres in northern Yemen, killing at least 11 people.
Another 19 people were injured in the attack in Abs, in Hajjah province, believed to have been carried out by the Saudi-led coalition which is backing Yemen's government in its fight against Houthi rebels.
The coalition has not yet commented.
Local people said the hit follows days of air raids in the area.
The first rescue workers to arrive at the scene had to move cautiously, fearing that the circling planes might attack again.
