According to Human Rights Watch: "At about 2:15 p.m. on January 16, 2016, an airstrike hit the Bio Pharma Factory, located in Sanhan, a village about 16 kilometers southeast of Sanaa city. Former Yemeni President Ali Abdullah Saleh, a key supporter of the Houthis in the current conflict, owns a house in Sanhan, his family’s ancestral village. The four-story factory produced medical capsules, syrup, tablets, and injections. It employed more than 100 workers before the war. During the conflict, after supplies became scarce and prices increased, the factory reduced its workforce to 60 workers. No workers were injured in the attack. The strike destroyed part of the roof of a factory building, several offices, a laboratory, and three vehicles. On the afternoon of January 16, Yehia Hussein al-Aush, a 33-year-old guard at the factory, was in the small guardhouse at the entrance to the factory compound. He said it was about an hour after the factory workers had finished their shift. He heard the roar of a plane overhead, and after about 10 minutes, the sound of the bomb whistling through the air. “[The bomb] hit the administrative building, where the laboratory and storehouse are,” al-Aush told Human Rights Watch. “I was disoriented and ran from my room.” Al-Aush believed that the area had been under aerial surveillance. “The planes have always been watching us,” he said. “You could hear the sound of airplanes that survey the area, but other factories in the area have not been hit.” Human Rights Watch examined the site on March 26, 2016. Muhammad Shewater, 63, the maintenance manager at the factory, told Human Rights Watch that the offices, laboratory, and the office of the factory director were destroyed in the strike. At least three vehicles parked in the factory compound were also damaged or destroyed. At the time Human Rights Watch visited, the factory continued to operate in buildings not affected by the airstrike. Workers had stopped using the building damaged in the bombing. Human Rights Watch also examined remnants found at the site and identified parts from the guidance kit for Paveway-series laser guided bomb. Markings on the fragments refer to ITT Enidine Inc., a New York company for hydraulic dampeners, indicating that a USbased company produced the guidance kit. The Bio Pharma company owns nine factories in Yemen, one of which was the factory struck in Sanhan. According to Shewater, the company’s products represent about 5 percent of the drug market in the country. Two workers told Human Rights Watch that there were no military targets in the immediate vicinity. “There’s no evidence to suggest that we are fighters or soldiers,” alAush said. “This is a civilian manufacturing area.” He and another worker mentioned that the “Sabra and Shatila” military camp is located about 10 kilometers to the south, while Jarban, a military storage location, is located about three kilometers away. The attack on the Bio Pharma factory was unlawful unless the factory was being used for military purposes, including to produce goods for military use. Human Rights Watch found no evidence of military goods at the site nor that the factory was bring used for military purposes. Researchers observed the remnants of medicine bottles, pill packets, and laboratory equipment at the site. The coalition should investigate the airstrike and if they unlawfully attacked the facility, compensate the factory owner for damage." ^[+]
