"Mahamat strongly condemns an attack by Israeli forces, that killed and wounded more than 100 Palestinians seeking life-saving humanitarian aid," the bloc said in a statement dated Friday but posted on X on Saturday.

"The Chairperson calls for an international investigation into the incident to bring the perpetrators to account," the statement said, urging "an immediate and unconditional ceasefire."

Israeli troops opened fire as Palestinian civilians scrambled for food supplies during a chaotic melee on Thursday that the Hamas-run territory's health ministry said killed more than 100 people in Gaza City.

The deaths came after a World Food Programme official had warned: "If nothing changes, a famine is imminent in northern Gaza."

Gaza's health ministry called it a "massacre," and said 115 people were killed and more than 750 wounded.

World leaders have called for an investigation, with President Joe Biden saying on Friday that the United States would start delivering relief supplies into Gaza via air drops — as some of its allies have already -- in a bid to get aid into hard-to-reach areas.

The aid convoy deaths helped push the number of Palestinian war dead in Gaza to 30,228, mostly women and children, according to the latest toll from the territory's health ministry.
