An air strike by the Saudi-led coalition on a primary school in northern Yemen on Tuesday killed five people including two children, medical and military sources said.
The headmaster and two other staff members were among those killed in the air raid in the district of Nihm, northeast of the capital Sanaa, which also left 13 wounded, the sources said.
A medical source at Kuwait Hospital in Sanaa confirmed the casualty toll.
Rights groups have repeatedly criticized the coalition over the civilian casualties inflicted by its air strikes on rebel-held regions.
In August, an air strike on a Koranic school in the northern Saada province killed 10 children and wounded 28 others, prompting a UN call for a swift investigation.
