Al-Zaydiya Security in Hudaydah governorate, Yemen





Type of weapon

US-made JDAM satellite guidance system


Between 8 and 9 p.m. on October 29, three airstrikes hit the al-Zaydiya security administration, 60 kilometers north of the city of Hodaida, in the Hodaida governorate. Beyond using the building as a jail, the Houthis and allied forces based military personnel and trucks mounted with machine guns at the facility, making it a legitimate military target. Human Rights Watch could not determine whether these personnel and vehicles were there at the time of the attack.

One of the three bombs that hit al-Zaydiya security directorate, Hodeida governorate, came through the ceiling next door to the director’s office. The attack killed at least 63 security personnel and detainees.

The destroyed remains of one of the wards in al-Zaydiya security directorate in Hodeida governorate.

Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs into all-weather precision-guided munitions. The JDAM is not a stand-alone weapon; rather it is a "bolt-on" guidance package that converts unguided gravity bombs into precision-guided munitions (PGMs). The key components of the system consist of a tail section with aerodynamic control surfaces, a (body) strake kit, and a combined inertial guidance system and GPS guidance control unit.
