According to Human Rights Watch: "The Saudi Arabia-led coalition fighting in Yemen carried out at least six apparently unlawful airstrikes in residential areas of the capital, Sanaa, in September and October 2015, killing 60 civilians. Coalition members and the United States, as a party to the conflict, are required under the laws of war to investigate such attacks, but they have not. Human Rights Watch found no evidence of any military target in an airstrike on the Old City and on al-Asbahi neighborhood in September. Airstrikes that caused civilian casualties on homes on Marib Street and in the neighborhoods of Hadda, al-Hassaba, and Thabwa hit 200 meters or more from possible military objectives. These attacks failed to distinguish civilians from military objectives or caused disproportionate civilian loss. Houthi forces in at least two of the attacks put civilians at unnecessary risk by deploying in densely populated neighborhoods.... On September 23, at about 7:30 a.m., two airstrikes hit Sanaa’s al-Asbahi neighborhood. The strikes killed 19 civilians, including two women and 10 children. The strikes destroyed three homes and damaged a four-story apartment building and three other multi-story houses. A local resident, Idris Radman, 27, showed Human Rights Watch the effect of the first strike, which destroyed three single-story houses. In the home of a taxi driver, Ahmed Maghreb, two people were killed. In the home of a police inspector, Ali al-Gharashi, seven were killed. In the third, the home of an oil company worker, Sayid al-Thubai, five were wounded. “I was sleeping with my family, and suddenly at around 7:30 a.m. something woke me and terrified me – a very extreme loud sound, an explosion,” said Najeeb Hussein, a 43-year-old oil industry worker. Five minutes later, the second strike hit a four-story apartment building, destroying the south-facing façade and damaging three more multi-story houses. The building housed the families of a barber, a painter, and a plumber. Mukhtar Dadya’s wife and three children were killed. Hisham Ghamdan, 35, a neighbor said that Dadya survived because he had gone to help at the scene of the first strike. “I was next to him when he found out that his whole family had been killed,” Ghamdan said. “It was a tragic, indescribable scene.” Ghamdan said he was sleeping when the first airstrike hit: Suddenly, I heard a very loud sound. I called my son, Ali, 16, to check what happened, because although I was used to hearing the loud sound of airstrikes, this one was very loud, and felt much closer than usual. My son returned within minutes terrified, pale, scared, crying and stuttering, “The rocket hit Ali al-Gharashi house’s, the rocket hit al-Gharashi’s house!” Zain al-Futaini, 43, who lives opposite the second apartment building that was hit, said he was lying in bed when he heard the first strike hit and then minutes later, the second. He thought they were probably not close because he did not know of any military targets in the area. But his building started to shake and bricks fell. He went outside: I saw one woman with a wound to her head, three children and two men lying on the ground, and one woman cut in half at the waist. My neighbors and I pulled three women and two children out of the basement of the apartment building. One [other] kid, who lived on the third floor of the building, had gone out onto the balcony after the first bomb to see what had happened, so when the second strike hit his building, he was blasted off the balcony and splattered onto the façade of the building opposite. Local residents said that no other airstrikes had hit the area. The home of Ali al-Thafif, a commander in the former Republican Guard, which has supported the Houthis, is 50 meters from the first strike site and 115 meters from second site. He and his family left their home at the beginning of the war, neighbors said, so it would not be a legitimate military target. An earlier airstrike hit his village home in Bayt al-Thafif, in Hamdan directorate, on June 8." ^[+]
