Thirty six civilians were killed when Saudi led warplanes bombarded a bottling plant in the northern Yemeni province of Hajjah on Sunday.
Residents reported that corpses burnt to pieces were pulled from the rubble of the plant.
Witnesses also reported another airstrike in the capital Sanaa that left four civilians dead after their home which is located near a military site was hit by a bomb.
Amnesty International reported earlier in the month that the campaign had left a “bloody trail of civilian death” which could amount to war crimes.
Last Friday, airstrikes killed sixty five people, mainly civilians, in Taiz.
An estimated four thousand five hundred people have been killed in five months of war in Yemen.
