"The strike is not the first incident in which #WCK staff were wounded in #Gaza. On Saturday, an IDF sniper fired at a car headed to a food warehouse in the Khan Yunis area…
The #WCK immediately filed a complaint with the IDF after the incident, & demanded the army stop the fire toward its staff, & guarantee their safety when distributing food in the Gaza Strip, which is carried out with full coordination"
