The Organisation of Islamic Cooperation (OIC) has condemned “the horrific massacres” committed by Israel following the uncovering of mass graves in the courtyard of the Nasser Medical Complex in Gaza’s Khan Younis, Al Jazeera reports.

“Hundreds of displaced, wounded, sick people and medical teams have been subjected to torture and abuse before being executed and buried collectively,” the organisation said in a statement.

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