At least 37 workers were killed when a dairy in western Yemen was bombed overnight, an official said on Wednesday after a seventh night of Saudi-led air strikes against Shiite rebels.
80 others were wounded at the plant in Hodeida, provincial governor Hasan al-Hai said, without specifying whether the factory was hit by an air strike or rebel shelling.
The head of the provincial health authorities, Abdulrahman Jarallah, gave a slightly different toll of 35 people killed and dozens wounded.
Part of the factory was destroyed and rescue teams were looking for survivors under the rubble, according to a medic at a Hodeida hospital that received the dead and wounded.
The circumstances of the bombing were unclear, with some witnesses saying the dairy was hit by a coalition air strike and others blaming rebel forces loyal to former president Ali Abdullah Saleh.
