Since the outbreak of the armed conflict in Yemen in late 2014, Mwatana for Human Rights has documented hundreds of ground attacks that have killed and injured thousands of civilians, including children, in various Yemeni governorates. These ground attacks have targeted civilian objects such as hospitals, schools, factories, bridges, historical and cultural monuments, water sources, funeral halls, weddings, and means of transportation. Mwatana defines ground attacks as any attack that has affected targets representing civilian objects or civilians, including children, using ground weapons such as Katyusha, mortars of different sizes, tanks and armored vehicles shells, artilleries of all kinds, RPG missiles, 12/7mm machine guns, and other heavy and medium ground weapons.
