A spokesperson for the Israeli Defense Force says it the organisation is aware of the incident and is investigating. It's the latest in a string of deadly incidents at Gaza aid sites.

Witnesses said the tanks fired at least two shells onto a route used by aid trucks. Medical facilities reported being overwhelmed by the attack, as Israel has pushed Gaza’s health system to near collapse after sustained attacks on hospitals and health sites.

At least 59 Palestinians were killed and more than 200 were injured while queuing for aid in Gaza after the military opened fire in Khan Younis on Jun. 17, according to Palestinian medics. The Israeli military acknowledged firing in the area and said it was looking into the incident.
