The Organization of Islamic Cooperation (OIC) condemned “the horrific massacres” committed by Israel following the uncovering of mass graves in the courtyard of Nasser Medical Complex in the city of Khan Younis in the southern Gaza Strip.

The organization said in a statement that “hundreds of displaced, wounded, sick people and medical teams have been subjected to torture and abuse before being executed and buried collectively”, Al Jazeera reported. 

It called for a probe into “a war crime, a crime against humanity, and organized state terrorism”, stressing the need for the International Criminal Court and the International Court of Justice “to assume their responsibilities in this regard”.

A mass grave with nearly 300 bodies has been uncovered by Gaza Civil Defense workers at the Nasser hospital in Khan Younis, following the withdrawal of Israeli troops on April 7.
