According to Amnesty International: "Many of the other civilian victims in the hospitals Amnesty International visited were injured by secondary explosions when attacks by Saudi Arabian-led coalition aircraft struck a weapons cache in the Mount Nuqum neighbourhood on 11 May. [...] Amnesty International interviewed four residents of Mount Nuqum who witnessed the attack and seven others who were injured in secondary explosions caused by the air strikes, including four children and two women. One of the women interviewed said that her son was killed in the same blast that had injured her. Around 40 people were killed in the strike according to the Ministry of Health, although Amnesty International could not independently verify this figure. Nearly 140 people injured in the attack were admitted for treatment at al-Thawra and Kuwait hospitals according to hospital staff and records." ^[+]
