According to Amnesty International: “The Saudi-led coalition used a precision-guided munition made in the United States in last week’s air strike on a detention centre in Sa’adah, north-western Yemen, which, according to Doctors without Borders, killed at least 80 people and injured over 200, Amnesty International said today. The laser-guided bomb used in the attack, manufactured by US defence company Raytheon, is the latest piece in a wider web of evidence of the use of US-manufactured weapons in incidents that could amount to war crimes. […] Under international humanitarian law, all parties to the conflict have a clear obligation to protect the lives of civilians caught up in the hostilities, including detainees. The deliberate targeting of civilian objects and extensive, unjustified destruction of property are war crimes. The coalition has denied targeting the detention centre in Sa’adah that was hit in the 21 January air strike. The United Nations described the attack as the “worst civilian-casualty incident in the last three years in Yemen”.” ^[+]
