According to Human Rights Watch: "Unlawful Airstrikes [...] Human Rights Watch investigated several coalition aerial attacks in Saada City that appeared to be in violation of the laws of war. On the basis of information from relatives, witnesses, medical staff, and local Houthi authorities Human Rights Watch compiled the names and ages of 59 people killed in aerial attacks in Saada City between April 6 and May 11, including 14 women and at least 35 children. [...] On May 5, an aerial attack struck the house of Muhammed al-Hibbi, killing his wife and all seven children when the roof collapsed on top of them, according to his cousin, Nuh Ahmed al-Hibbi. Human Rights Watch did not visit the impact site, but medical staff corroborated the number of casualties." ^[+]
