According to Human Rights Watch: "Coalition aircraft struck the Amran Cement Factory in three separate attacks on July 12, 2015, February 3, 2016, and February 15, 2016. On July 12, at about 12:45 p.m., at least five bombs hit different parts of the cement factory including the heating tower, the mixing area, and the water tank. The factory management had closed the factory after the coalition naval blockade made it difficult for them to source fuel and raw materials. Just a few days before the attack, they reopened the factory, and on July 11, workers started up the factory’s main production line. Coalition forces attacked the factory the next day, wounding 12 workers, including 7 with more serious injuries. After the attack, the factory gave most of the factory’s 1,500 workers leave, retaining only 350 workers to fulfill security, administrative, IT, and maintenance tasks." ^[+]
