According to residents and plant workers, at least six consecutive strikes pounded the housing compound, several targeting the compound cafeteria and maintenance equipment store. The coalition targeted a small residential compound 700m to the north of the steam power plant also used to house plant workers.
Amnesty International delegates at the site found no evidence that the residential compounds were being used for any military purposes. According to scores of residents interviewed by Amnesty International, no Huthi fighters were present in the compound, which also housed several families displaced by the conflicts in Ta’iz, Aden and surrounding areas. The nearest military objective, an air force base, is located approximately 800m south east of the residential compounds. It is unclear whether it was also targeted.

Starting between 9:30 and 10 p.m. on July 24, 2015, coalition airplanes repeatedly struck two residential compounds of the Mokha Steam Power Plant, which housed plant workers and their family members.

Human Rights Watch report

One resident describing the aftermath of an attack on a residential compound inhabited by power plant workers in Mokha on 24 July said “corpses and heads” were scattered everywhere “engulfed by fire and ashes”, comparing the sight to a scene from “judgement day”. Another local resident told Amnesty International he continued to be haunted by the memories of walking through the“pools of blood and severed limbs” of more than 20 victims.

Khalil Abdullah Idriss, 35, a nurse at the plant’s clinic, said that he rushed to al-Salam clinic in Mokha City when he heard news of the attack.[117] There, he and other medics administered basic first aid, then sent the wounded on to hospitals in Hodaida. He said that within an hour of the airstrikes, they had received at least 30 wounded and eight bodies.

Early in the morning of July 25, a news ticker on Al-Arabiya TV, a Saudi-owned media outlet, reported that coalition forces had attacked a military air defense base in Mokha. The ticker was swiftly taken down and the story can no longer be found anywhere on Al-Arabiya’s website. Human Rights Watch identified a military facility about 800 meters (875 yards) southeast of the Mokha Steam Power Plant’s main compound, which plant workers said had been a military air defense base. The plant workers said that it had been empty for months, and Human Rights Watch saw no activity or personnel at the base from the outside, except for two guards.
