According to Ceasefire Centre for Civilian Rights and Mwatana for Human Rights: "Between March 26, 2015, when the Saudi/UAE-led coalition announced the start of its military operations in Yemen, and December 31, 2019, Mwatana documented at least 153 coalition airstrikes on or impacting schools and educational facilities in 16 governorates in Yemen, including Saada, Hajjah, the capital secretariat (Sana’a), Sana’a province, Abyan, Al-Bayda, Al Dhale’e ,Al-Hodeidah, Al-Jawf, Al-Mahwit, Amran, Dhamar, Lahj, Marib, Shabwah, and Taiz. In 140 of these cases, Mwatana researchers and witnesses interviewed by Mwatana did not identify military targets near or in the school that was damaged or destroyed by an airstrike. These Saudi/UAE-led coalition bombings form part of a pattern of attacks on civilian objects which appear to be indiscriminate. In 13 of the documented airstrikes on or impacting schools, Mwatana researchers found the schools were being used by armed groups, or interviewees reported suspicions of military presence in or near the school. In some cases, fighters were using the school facility as a meeting place, for housing, or the kitchen for cooking. In other cases, interviewees reported suspicions that the school was being used as a warehouse by an armed group or of a military presence in or near the school at the time of the attack, for example checkpoints, military vehicles, gunmen, or military mobilizers. In many of these cases, it appears that the damage caused to civilians, including damage or destruction of the school, exceeded any concrete military advantage from attacking the military target identified or suspected. [...] Around midnight, on Saturday, April 7, 2018, Saudi/UAE-led coalition aircraft bombed Imam Ali bin Abi Talib Basic School in Al-Qala (the Castle) area, Razih district, Saada governorate. The attack, conducted with one bomb, resulted in the partial destruction of the school. " ^[+]
