According to Human Rights Watch: "Human Rights Watch located remnants of US-made weapons at the site of coalition airstrikes in Arhab in Sanaa governorate and in the Hodeida governorate. A September 10 attack on a drilling site for water in Arhab killed at least 31 civilians, including three children. Human Rights Watch researchers found remnants of two US-made GBU-12 Paveway II laser guided 500-pound bombs. One Paveway II laser guidance system had markings indicating it was manufactured by Raytheon, Inc., a US arms manufacturer, dated October 2015 – seven months after the start of the war. The other weapon was manufactured at an undetermined date in 2015. By October 2015, the UN as well as Human Rights Watch and others had already reported numerous unlawful attacks by coalition forces.... Before dawn on September 10, coalition aircraft struck the site of a water drilling rig near Beit Saadan village in the Arhab district, 30 kilometers north of Sanaa. The drill rig was in an unpopulated area reachable only by dirt road, about two kilometers from the nearest village. Multiple strikes over the course of the morning killed at least 31 civilians and wounded 42 more, according to OHCHR. The first strike hit near a workers’ shelter occupied by nearly a dozen workers and managers, killing six and wounding five others. At about 9 a.m., after several dozen villagers came to remove the bodies of those killed and examine the site, three planes returned and proceeded to bomb the vicinity at least 12 more times, about 15 minutes apart, witnesses said. The strikes lasted until about noon, killing at least 15 civilians, and wounding dozens more. Human Rights Watch independently confirmed the names and ages of 21 people who died in the attack, including three boys ages 12, 14, and 15. Yehia Abdullah, a 34-year-old teacher, said he spent the evening with his brother Muhammed and other workers at the site. His brother died in the first strike. Abdullah, who had left the site 20 minutes earlier, was on his way back when he heard the bombing: I saw the light of a bomb on the site of the drill rig. I tried to reach them by phone, but no one answered. … I arrived while the drill machine was operating and saw scattered and charred bodies. Everyone was in his place where he had been working or sitting. I saw five bodies including my brother Muhamad. First I found my brother’s severed leg outside the [workers’ shelter], about six meters, his arm on the door … and half his body buried in the ruins. Salim al-Sadani, a local farmer, said that when he learned that his uncle Mahdi al-Sadani had died in the airstrike, he went to the site, arriving at about 8 a.m. About 300 people, including the dead’s relatives, [were there] to remove the bodies. … I saw two warplanes arriving from the south. Between 8 and 9 a.m., I saw the missile coming down to ground as I was [here] next to my uncle's body. Sadani said he lost consciousness briefly when the strike threw him to the ground: I saw myself full of blood and ran away. I just saw smoke and flame. I saw a body of an old man in front of me, he is from [Thinah], the neighboring village. He was dead. I was taken to [the] hospital. I was injured by [fragments] in the left hand … as well as [fragments] in my back. Several witnesses said that three coalition planes circled overhead, striking the area in widening circles as those gathered attempted to escape. People ran in all directions to escape the bombing, they said. Human Rights Watch visited the site on November 10, and examined the rubble of the workers’ shelter, as well as the burned wreckage of a fuel tanker truck. There were at least 11 bomb craters or impact sites in the immediate area. Footage of the site taken the day of the strikes shows many burned and mutilated bodies. Human Rights Watch examined and photographed remnants of a US-made GBU-12 Paveway II laser guided 500-pound bomb. A part of the guidance system (wing assembly) was produced by Raytheon in the US in October 2015, according to markings on the remnants. Residents of Beit Saadan said that they had pooled together 22 million Yemeni Rials (US$88,000) of their personal funds to pay to drill the well to supply drinking water to their village. The bombing occurred on the last day of planned drilling, after the villagers had struck water, a local farmer said. Several witnesses said that no Houthi fighters or military equipment were stationed in the area before the strikes. When Agence France Presse questioned a coalition spokesman, Gen. Ahmed al-Assiri, about the attack, he replied, “All our strikes in that area target Houthi positions.” The coalition has not announced an investigation into the attack. Deliberate or indiscriminate attacks on civilians and civilian infrastructure are a serious violation of the laws of war, and if carried out intentionally or recklessly are war crimes." ^[+]
